ADA4091-2ACPZ-R7

Overview

The ADA4091-2ACPZ-R7 is a dual-channel micropower operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply from 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 1.22 MHz, a slew rate of 0.46 V/µs, and a maximum offset voltage of 250 µV at ±1.5 V. The device draws 200 µA per amplifier and includes overvoltage protection allowing inputs to exceed supply rails without phase reversal.

Feature Summary

• Features integrated overvoltage protection circuitry that allows input voltages to safely exceed either supply rail without causing phase reversal or latch-up.
• Provides full rail-to-rail signal swing at both the input and output stages, enabling high signal-to-noise ratios in single-supply systems.
• Utilizes a unique input stage architecture combining PNP and NPN differential pairs to maintain linear operation across the entire common-mode voltage range.

Applications

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

Procurement Notes

Verify the specific package variant and tape-and-reel configuration against the manufacturer's current ordering guide. Confirm that the component meets all required environmental and safety standards for the intended deployment environment before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring low power consumption alongside precision amplification in single-supply environments. The wide input voltage range and overvoltage tolerance make it suitable for interfacing with transducers that may produce signals exceeding standard supply limits.

Part Context
