The LPV531 is an extremely versatile operational amplifier. A single external resistor gives the system designer the ability to define the quiescent current, gain bandwidth product and output short circuit current. This innovative feature gives the system designer a method to dynamically switch the power level to optimize the performance of the op amp and meet the system design requirements.

The LPV531 can be tailored to a wide variety of applications. It offers the system designer the ability to dynamically trade off supply current for bandwidth by adjusting the current drawn from the ISEL pin using a DAC or switching in different value resistors in series with the ISEL pin. The LPV531 is capable of operating from 73 kHz, consuming only 5 μA, to as fast as 4.6 MHz, consuming only 425 μA. The input offset voltage is relatively independent and therefore is not significantly affected 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.

Offered in the space saving 6-pin SOT package, the LPV531 is ideal for use in handheld electronics and portable applications. The LPV531 is manufactured using TI’s advanced VIP50 process.

A fixed supply current/gain bandwidth is available upon request.
