| LPV531 Programmable CMOS Input, Rail-to-Rail Output Operational Amplifier PRELIMINARY March 2006 LPV531 Programmable CMOS Input, Rail-to-Rail Output Operational Amplifier General Description The LPV531 is an extremely versatile operational amplifier. A single external resistor gives the system designer the ability to program the quiescent current, gain bandwidth product and output short circuit current. This innovative feature gives the system designer a method to dynamically optimize the performance of the op amp to meet the system design requirements. The LPV531 can be tailored to a wide variety of applications, it offers the system designer the ability to trade off supply current for bandwidth. The LPV531 is capable of operating from 73 kHz, consuming only 5 A, to as fast as 4.6 MHz, consuming only 425 A. The input offset voltage is relatively independent and therefore is not effected by the chosen power level. Utilizing a CMOS input stage, the LPV531 achieves an input bias current of 50 fA and a common mode input voltage which extends from the negative rail to within 1.2V of the positive supply. The LPV531's rail-to-rail class AB output stage enables this op amp to offer maximum dynamic range at low supply voltage. Available in the space saving 6-pin SOT23 package, the LPV531 is ideal for use in handheld electronics and portable applications. The LPV531 is manufactured using National's advanced VIP50 process. A fixed supply current/gain bandwidth is available upon request.

Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics Tables. Note 2: Human Body Model is 1.5 k in series with 100 pF. Machine Model is 0 in series with 200 pF. Note 3: Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150C. Note 4: The maximum power dissipation is a function of TJ(MAX), JA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) - TA)/ JA . All numbers apply for packages soldered directly onto a PC board. Note 5: Typical values represent the most likely parametric norm. Note 6: All limits are guaranteed by testing or statistical analysis. Note 7: Slew rate is the slower of the rising or falling slew rates. Note 8: Offset voltage average drift is determined by dividing the change in VOS at temperature extremes into the total temperature change.
