_________________________________________________________________ maxim integrated products 7 detailed desc ription of software the max5725a ev kit software can evaluate the spi interface max5725a family of 12-/10-/8-bit dacs. the main software window has three tabs: dacs , scripts , and configuration status . within the dacs tab sheet (figure 2), the user can set the reference and dac outputs. the scripts tab sheet (figure 3) allows the user to send a sequence of write commands to the eight dacs, and load and save the write sequence. the configuration status tab sheet (figure 4) displays the configuration settings for each dac. in addition, the soft - ware allows the user to adjust the configuration, power, reset, and default settings. demo mode the ev kit software enters the demo mode when the usb connection is not detected. when in demo mode, all communication to the ev kit is disabled; however, most of the software is functional. demo mode allows the user to evaluate the software without hardware connectivity. part selection the user must select the appropriate radio button in the part selection group box that corresponds to the installed maxim ic dac bits. spi interface when the software first starts up, the spi radio button is selected automatically. if the user selects the i2c radio button, then the software searches for a valid i 2 c address that is on the bus. if no address is found, the software returns to the spi radio button selection. the ev kit is capable of evaluating i 2 c parts by replac - ing u1. once the i 2 c part is installed, refer to the i 2 c address section in the max5825a ev kit data sheet. reference the reference default configuration is set to 2.5v using the external voltage reference ic (u7). the external 2.5v reference can be connected between the ext_ref pin and its corresponding ground. select the external ref radio button and type the reference voltage into the edit box. removing the shunt from jumper ju11 allows internal reference options that include 2.048v, 2.5v, and 4.096v selection using the corresponding radio buttons. make sure the vdd supply is greater or equal to the volt - age reference selected for proper operation. when the ev kit uses the on-board 3.3v supply to power the ic, the 4.096v radio button selection will not provide the 4.096v. dac commands within the dacs tab sheet (figure 2), the user can set the output of the dacs with two options. the first option is the quick dac output voltage group box that allows the user to write and load the code to all the dacs. set the desired output for each dac using the correspond - ing slider and press the execute button. the second option is to write the return code, write the code, load the code, or write and load the code to the desired dac using the drop-down lists and edit box within the command group box. press the execute button once all the settings are appropriately configured. dac commands (script) within the scripts tab sheet (figure 3), enter the desired data on the left and choose the appropriate command from the drop-down list. pressing the execute button writes to the code and/or dac registers and the script status changes from incomplete to complete . refer to the max5725a ic data sheet for a list of possible commands. if a sequence of commands needs to be performed, adjust all data edit boxes and command drop-down lists accordingly, and press the execute all button. to reset the script status to incomplete , press the reset script button. data logging using the save button, the sequence of commands can be saved into a text file format. to recall the sequence, press the load button and select the appropriate text file. configuration status the configuration status tab sheet (figure 4) displays the current status of the configuration, power, and default settings for each dac. read back the ev kit reads back the return, code, dac, and watchdog values. check the inc checkbox to increment the address pointer and select the appropriate radio button to set the dout phase equal to 0 or 1 when reading back. select the appropriate read radio button and press the execute button in the read back group box. asynchronous clr a checked clr asserted checkbox drives the clr pin of the ic low, which clears the content of both code and dac registers. unchecking the clr asserted checkbox drives the clr pin high and writing new commands is allowed again. asynchronous ldac a checked ldac asserted checkbox drives the ldac pin of the ic low, which allows writing to the code register and then automatically transfers to the dac register to change the dacs output. unchecking the ldac asserted checkbox drives the ldac pin high. to change the dac outputs, the user must write to the code registers, and then write to the dac registers. evaluates: MAX5723/max5724/ max5725a/max5725b max5725a evaluation kit
_________________________________________________________________ maxim integrated products 8 interface watch dog use the mask checkbox, timeout edit box, and safety level radio buttons to set the watchdog. the timeout time range that can be entered into the edit box is 1 ms to 4095 ms. the user must allow enough timeout time to send data to the dac(s). it is recommended that the user set the timeout time to the maximum time of 4095ms, because the time windows takes to communicate with the part may vary. in addition, configure the dac output settings before pressing the execute button. the irq circle changes from white to red when the irq signal goes low. refer to max5725a ic data sheet for detailed description. configuration the configuration command includes the watch dog radio buttons and the gate_enb , ldac_enb , and clear_enb checkboxes for selected dac(s). see the configuration status tab sheet to monitor the settings on each dac. refer to max5725a ic data sheet for detailed description. power the power command is selectable for individual dacs. when a dac is selected, the channel is active. other options include powering down with 1k i termination to gnd, 100k i termination to gnd, and high imped - ance. once the appropriate selection is made, press the execute button. reset the reset command allows the user to set or clear the gate, refresh or reset the watchdog timer, or issue a soft - ware reset or clear. refer to max5725a ic data sheet for detailed description. default the default command allows the user to set the default settings for individual dacs. refer to max5725a ic data sheet for detailed description. advanced user interface there are two methods for communicating with the ic. the first is through the window shown in figure 2. the second is through the advanced user interface win - dow shown in figure 4. the advanced user interface window becomes available by selecting the options | interface (advanced user) menu item and allows execution of serial commands manually. this interface is not recommended unless the user has to change individual bit s in the interface. figure 5. advanced user interface window (3-wire interface tab) evaluates: MAX5723/max5724/ max5725a/max5725b max5725a evaluation kit
_________________________________________________________________ maxim integrated products 9 figure 6. jumper callouts detailed description of hardware the max5725a ev kit provides a proven layout for the max5725a ic. an on-board external 2.5v reference (max6173), usb interface circuitry, and jumpers to disconnect the on-board microcontroller are included on the ev kit. user-supplied power supply the ev kit is powered completely from the usb port by default. to power the ic with a user-supplied power sup - ply, move the shunt on jumper ju10 to the 2-3 position and apply a 2.7v to 5.5v power supply at the vdd_ext and the nearest gnd pcb pads on the ev kit. the on-board external 2.5v voltage reference (u7) is powered from the usb interface circuit when a shunt is installed in the 1-2 position on jumper ju13. to use the same external supply applied at the vdd_ext pcb pad, move the shunt to the 2-3 position on ju13. user-supplied reference the on-board voltage reference (u7) generates a voltage reference of 2.5v. the user can apply an external voltage reference by moving the shunt on jumper ju11 to the 2-3 position and applying 2v to vdd at the ref_ext pcb pad on the ev kit. if the internal reference is selected, the ref pin becomes an output. in this case, ju11 should be removed. user-supplied spi to evaluate the ev kit with a user-supplied spi bus, remove shunts from jumpers ju1Cju4. apply the user- supplied cs , sclk, din, and dout signal to header pins h1-1, h1-3, h1-5, and h1-7, respectively. connect the user-supplied spi ground to header pins h1-2, h1-4, h1-6, and h1-8. user-supplied irq , clr , and ldac remove the shunts from jumpers ju5 and ju6. apply the user-supplied irq , clr , and ldac to header pins h1-11, h1-15, and h1-17, respectively. connect the user-supplied signal ground to header pins h1-12, h1-16, h1-18. evaluates: MAX5723/max5724/ max5725a/max5725b max5725a evaluation kit
