ADA4091-2ARZ

Overview

The ADA4091-2 is a dual-channel micropower operational amplifier featuring rail-to-rail input and output capabilities. It operates from a single supply of 3.0 V to 30 V or dual supplies of ±1.5 V to ±15 V. Key electrical specifications include a gain bandwidth product of 1.27 MHz, a slew rate of 0.46 V/µs, and a maximum input offset voltage of 250 µV at 25°C. The device draws 200 µA per amplifier and includes integrated overvoltage protection (OVP) allowing inputs to exceed supply rails safely.

Feature Summary

Features integrated overvoltage protection circuitry that allows input voltages to exceed supply rails without phase reversal or latch-up.
Provides rail-to-rail input and output swing capability for maximizing dynamic range in low-voltage systems.
Operates on a wide single-supply voltage range from 3.0 V to 30 V with micropower consumption.

Applications

Industrial process control
Battery-powered instrumentation
Power supply control and protection
Remote sensors

Procurement Notes

Verify the specific package variant required, as the component is available in 8-lead SOIC and LFCSP configurations. Confirm that the ordering suffix matches the desired tape and reel quantity if applicable. Ensure the selected part number aligns with the intended temperature range and performance requirements for the final design.

Selection Notes

Select this component when high precision is required alongside low power consumption in single-supply environments. The integrated overvoltage protection makes it suitable for applications where input signals may transiently exceed the supply voltage. Consider the 1.2 MHz bandwidth and low noise density for signal conditioning tasks involving transducers like Hall effect or piezoelectric sensors.

Part Context

The ADA4091-2 belongs to Analog Devices' family of 36 V, low-power operational amplifiers. It is the dual-channel counterpart to the quad-channel ADA4091-4. Both variants share identical electrical characteristics and are designed for portable telecommunications equipment and interface circuits for transducers with wide output ranges.
