ADA4077-2TRMZ-EP

Overview

The ADA4077-2TRMZ-EP is a dual-channel high-precision amplifier from Analog Devices, designed for demanding environments. It features an extended industrial temperature range of −55°C to +125°C and operates on dual supplies from ±2.5 V to ±15 V. Key electrical specifications include a maximum offset voltage of 90 µV at 25°C and 220 µV across the full temperature range, with a drift of 1.2 µV/°C. The device offers a gain bandwidth product of 3.9 MHz, a slew rate of 1.2 V/µs, and low supply current of 400 µA per amplifier. It provides CMRR and PSRR exceeding 120 dB minimum.

Feature Summary

• Supports defense and aerospace applications through AQEC standards with controlled manufacturing baselines.
• Features extremely low offset voltage and drift for high accuracy signal conditioning.
• Outputs remain stable with capacitive loads exceeding 1000 pF without external compensation.

Applications

• Process control front-end amplifiers
• Wireless base station control circuits
• Optical network control circuits
• Precision filters

Procurement Notes

Verify that the specific ordering suffix matches the required packaging format, as the EP designation indicates Enhanced Product status suitable for defense and aerospace sectors. Confirm compliance with the specified moisture sensitivity level and assembly site requirements during procurement to ensure adherence to quality standards.

Selection Notes

Select this component when operation in extreme temperatures between −55°C and +125°C is mandatory. It is appropriate for designs requiring strict control over offset voltage drift and low noise density. Ensure the application benefits from its unity-gain stability and phase reversal prevention characteristics.

Part Context

This part belongs to the ADA4077 series of precision amplifiers, specifically the dual-channel variant. The -EP suffix designates it as an Enhanced Product, distinguishing it from standard commercial versions by offering controlled manufacturing processes and qualification data availability for rigorous industry standards.

Replacement Considerations

Standard commercial variants such as ADA4077-2ARMZ or ADA4077-2BRZ offer similar electrical performance but lack the enhanced product controls and extended temperature baseline required for aerospace applications.
