Typical Application

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.
