ADA4091-4 Precision, Micropower, OVP, RRIO Quad Op Amp

The ADA4091-2 dual and ADA4091-4 quad are micropower, single-supply, 1.2 MHz bandwidth amplifiers featuring rail-torail inputs and outputs. They are guaranteed to operate from a +3.0 V to +30 V single supply as well as from ±1.5 V to ±15 V dual supplies.

The ADA4091-2 / ADA4091-4 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 (OVP).

Applications for these amplifiers include portable telecommunications equipment, power supply control and protection, and interface for transducers with wide output ranges. Sensors requiring a rail-to-rail input amplifier include Hall effect, piezoelectric, and resistive transducers.

The ability to swing rail-to-rail at both the input and output enables designers, for example, to build multistage filters in single-supply systems and to maintain high signal-to-noise ratios (SNR).

The ADA4091-2 / ADA4091-4 is specified over the extended industrial temperature range of −40°C to +125°C. The ADA4091-2 / ADA4091-4 is part of the growing selection of 36 V, low power operational amplifiers from Analog Devices, Inc.,

The ADA4091-2 is available in 8-lead, plastic SOIC and 8-lead LFCSP packages. The ADA4091-4 is available in 14–lead TSSOP and 16-lead LFCSP surface-mount packages.
