ADA4097-2HRZ-RL7

Overview

The ADA4097-2HRZ-RL7 is a dual-channel, precision operational amplifier from Analog Devices. It features an ultrawide common-mode input range extending to +VS + 70 V and supports supply voltages up to 50 V. Key electrical parameters include a typical gain-bandwidth product of 130 kHz, a maximum input offset voltage of ±60 µV, and a low quiescent current of 32.5 µA per channel. The device operates within a temperature range of -55°C to +150°C.

Feature Summary

• Over-The-Top operation allows the input common-mode voltage to exceed the positive supply rail by up to 70 V without phase reversal.
• Robust design with high electrostatic discharge tolerance and large signal voltage gain exceeding 120 dB.
• Low power consumption with a shutdown feature that reduces supply current significantly when inactive.
• Unity-gain stability ensures reliable performance in various feedback configurations.

Applications

• Industrial sensor conditioning
• Supply current sensing
• Battery and power supply monitoring
• Front-end amplifiers in abusive environments

Procurement Notes

Verify the specific package type and grade (H) against the datasheet requirements for your application. Confirm that the ordering suffix matches the desired reel quantity and packaging format. Ensure compatibility with your PCB footprint and thermal management strategy before finalizing procurement.

Selection Notes

Select this component for applications requiring over-the-top input capability and high voltage operation. Consider the H grade for extended temperature ranges up to 150°C. Evaluate the low bias current and noise specifications for precision signal processing needs.

Part Context

This part belongs to the ADA4097 family of robust, precision op amps. It is designed for industrial and automotive environments where inputs may exceed supply rails. The dual-channel configuration provides two independent amplifiers in a single package.

Replacement Considerations

Check for direct pin-compatible alternatives within the Analog Devices portfolio that offer similar over-the-top capabilities and voltage ratings. Verify that any substitute meets the required temperature range and electrical specifications.

FAQ

What is the maximum common-mode input voltage?

The common-mode input range extends from -VS - 0.1 V to -VS + 70 V, allowing operation beyond the positive supply rail.

Does the device support shutdown functionality?

Yes, the ADA4097-2 includes shutdown pins (SHDNx) that allow the amplifier to be placed in a low-power state, reducing supply current to a maximum of 20 µA.

What is the operating temperature range?

The H grade version supports an extended operating temperature range from -55°C to +150°C.
