LV4993M no.a1962-6/13 cautions for use 1. input coupling capacitor (c3) c3 is an input coupling capacitor, and it has aimed at the dc cutting. however, please set it in consideration of the cutoff frequency when you decide the capacitance value so that the high-pass filter may be composed by this capacitor (c3) and input resistance (r1), and the bass frequency signal may attenuate. the cutoff frequency is shown by the next formula. fc = 1 2 *c3*r1 moreover, this capacitor influences a pop noise at start-up. please note it enoug h so that the charging time to the capacitor may become long when the value is enlarged, and the pop noise level may grow. 2. btl voltage gain the voltage gain of the first amplifier is decided depending on the ratio of resistance r1 and r2. vg=20 * log(r2/r1) (db) therefore, the btl voltage gain: vgbtl=6+20 * log(r1/r2) (db) it is shown by the above-mentioned calculating formula. please set the btl voltage gain within the range from 0 to 26db. 3. pin 3 capacitor (c4) c4 is a capacitor for the ripple filter. it is a purpose to compose the low-pass filter of internal resistance (100k ? +450k ? ) and c4, to reduce the power supply ripple element, and to improve the ripple elimination factor. please operate the automatic pop noise reduction circuit by us ing the standing up transition response characteristic of 3rd pin voltage (standard voltage), and design in ic in consideration of a pop noise at the time of start-up growing when the c3 capacity value is reduced to hasten the start-up speed. 4. capacitor for power supply line (c1, c2) bypass capacitor (c2) has aimed at the high frequency aphaeresis that cannot be removed with the power supply capacitor (c1: chemical capacitor). this capacity must arra nge as much as possible near ic, and use the ceramic capacitor with good high-frequency property. it is also possible to bring it together in the ceramic capacitor of one 2.2 f when a steady power supply is used. please enlarge the capacity value of power supply capacitor (c1) when the power supply line is comparatively unstable. 5. standby pin (pin 2) by controlling the standby pin, the mode changeover can be made between standby and operation modes. the series resistance (r3:1k ? or more) is recommended to be inserted might r eceive the influence of a digital noise from cpu though it is possible to control with the output port of cpu directly. standby mode ? v2 = 0 to 0.3v operation mode ? v2 = 1.6 to 3v please suppress the impressed voltage to become a static test mode (heat protection circuit operation check mode) when 3v or more is impressed to 2nd pin within 3v. mo reover, it is also possible to synchronize with the power supply and to use the pin as shown in figure 1 when the standby function is not used. please set the value of series resistance (r3) so that 2nd pin voltage may become 3v or less. current (i 2 ) that flows in 2nd pin can be calculated by the next formula. i 2 = 7*10 -6 +(v cc ? 0.7) r3+30000 fig. 1 v cc r3 v cc stby 7 2
LV4993M no.a1962-7/13 6. pin 4 control (second amplifier stop control function) pin 4 are pin that control on/off as for the movement of th e second amplifier of the btl amplifier. the switch of the speaker drive (btl output method) and the earphone drive (shingle end output method) can operate by using this function. moreover, it is possible to use it as a voice mute function in the btl output method. second amplifier on ? v4 = 1.6 to v cc or open second amplifier off ? v4 = 0 to 0.3v make it to the opening when this function is not used. 7. load capacitance the phase margin degree of the power amplifier might decreas e by the influence of this capacitor when the capacitor is connected by the purpose of the anti- electric wave radiation measures etc. between output pins gnd and the oscillation be caused. note the capacity value when you add this capacitor. recommended capacity value: 100pf or less or 1000pf to 1 f 8. thermal protector circuit the thermal protector circuit is built into in ic, and when heat is abnormally generated because of some causes, the risk of destruction/deterioration can be reduced. the protection circuit operates when junction temperature (tj) of the chip in ic rises to about 165 , the current supply source to the power amplifier is intercepted, and the signal is not output. it returns automatically if the temperature of the chip decreases (about 140 ). this circuit must note handling enough because it is able surely not to prevent destruction/dete rioration. turn off power pr omptly when you abnormally generate heat, and pinpoint the cause. 9. short-circuit between pins when power is applied with pins left short-ci rcuited, deterioration or damage may result. therefore, check before power application if pins are shor t-circuited with solder, etc. during mounting of ic to the substrate. 10. short-circuit of load if the load is left short-circuited for a long peri od of time, deterioration or damage may occur. never allow the load to short-circuit. 11. maximum rating when ic is used near the maximum rating, there is a po ssibility that the maximum rating may be exceeded even under the smallest change of conditions, resulting in failure. take the sufficient margin for variation of supply voltage and use ic within a range where the maximum rating will never be exceeded.
