ADA4091-2ARZ-R7

精密微功耗， OVP ， RRIO运算放大器 Precision Micropower, OVP, RRIO Operational Amplifier

GENERAL DESCRIPTION

The ADA4091-2 dual and ADA4091-4 quad are micropower, single-supply, 1.2 MHz bandwidth amplifiers featuring rail-to rail inputs and outputs. They are guaranteed to operate from a +2.7 V to +30 V single supply as well as from ±1.35 V to ±15 V dual supplies.

The ADA4091 family features a unique input stage that allows the input voltage to exceed either supply safely without any phase reversal or latch-up; this is called overvoltage protection, or OVP.
