ADA4091-2ACPZ-RL

Overview

The ADA4091-2ACPZ-RL is a dual micropower precision operational amplifier featuring rail-to-rail input and output capabilities. It operates from single supplies 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 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 that allows input voltages to exceed supply rails without phase reversal or latch-up.
• Provides rail-to-rail input and output swing capability for enhanced design flexibility in single-supply systems.
• Delivers micropower performance with low supply current consumption suitable for battery-powered applications.

Applications

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

Procurement Notes

Verify the specific package type and tape/reel configuration against the manufacturer's ordering guide before procurement. Confirm that the ACPZ suffix corresponds to the LFCSP package variant required for your PCB layout. Ensure compatibility with your assembly processes regarding thermal resistance and soldering profiles specified in the datasheet outline dimensions.

Selection Notes

Select this component when high precision is required alongside low power consumption and wide input voltage ranges. The rail-to-rail I/O feature makes it suitable for interfacing with transducers having wide output ranges. Consider the OVP capability if the application environment poses risks of input overvoltage conditions relative to the supply rails.

Part Context

This part belongs to the ADA4091 family of low-power, 36 V operational amplifiers manufactured by Analog Devices Inc. The family includes dual (ADA4091-2) and quad (ADA4091-4) variants available in various surface-mount packages such as SOIC, TSSOP, and LFCSP. It is designed for applications requiring precision amplification under strict power constraints.

Replacement Considerations

Consult the manufacturer's documentation for direct pin-compatible alternatives within the same family, such as the ADA4091-4 for quad-channel requirements. Verify that any substitute maintains the required overvoltage protection specifications and rail-to-rail input/output characteristics.
