ADA4097-2BCPZ

Overview

The ADA4097-2BCPZ is a dual-channel, precision operational amplifier manufactured by Analog Devices Inc. It features an ultrawide common-mode input range extending from −VS to +VS and beyond, supporting Over-The-Top operation up to 70 V. The device operates on supply voltages ranging from +3 V to +50 V with a typical quiescent current of 32.5 µA per channel. Key electrical specifications include a gain-bandwidth product of 130 kHz, a maximum input offset voltage of ±60 µV, and a low input offset voltage drift of ±1 µV/°C for the B grade. It provides high common-mode rejection (120 dB minimum) and power supply rejection (123 dB minimum), ensuring robust performance in demanding industrial environments.

Feature Summary

• Over-The-Input capability allows signal inputs to exceed the positive supply rail without phase reversal or damage.
• Robust design includes high electrostatic discharge tolerance and large-signal voltage gain exceeding 120 dB.
• Low power consumption with shutdown functionality available for specific package variants to minimize standby current.

Applications

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

Procurement Notes

Verify the exact package type and temperature grade against the datasheet ordering guide before procurement. Confirm that the B-grade specification aligns with your offset voltage requirements. Ensure proper ESD handling procedures are followed during storage and assembly due to the sensitivity of the CMOS input stages.

Selection Notes

Select this component when high-voltage common-mode signals must be processed relative to a lower supply rail. The B-grade variant offers tighter offset voltage limits compared to the H-grade. Consider the LFCSP package if thermal dissipation and board space are critical constraints.

Part Context

This part belongs to the ADA4097 family of robust, precision op amps designed for high-voltage sensing. It complements single-channel and quad-channel variants within the same series, sharing identical electrical characteristics but differing in pin count and package configuration to suit various integration needs.

Replacement Considerations

Direct substitutes within the same family include the ADA4097-1 for single-channel applications or other packages like MSOP and SOIC_N for form-factor changes. Verify that any replacement maintains the Over-The-Top input capability and similar quiescent current specifications.
