ADA4077-2TRMZ-EPR7

Overview

The ADA4077-2TRMZ-EPR7 is a dual-channel high-precision amplifier from Analog Devices, designed for demanding industrial environments. It features an extended operating 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 a maximum drift of 1.2 µV/°C across the full temperature range. The device offers a gain bandwidth product of 3.9 MHz, a slew rate of 1.2 V/µs, and a typical supply current of 400 µA per amplifier. It provides low input bias current (1 nA max) and low voltage noise density (6.9 nV/√Hz).

Procurement Notes

Verify the specific Enhanced Product suffix (EP) requirements against project specifications. Confirm that the extended temperature range and controlled manufacturing baseline align with system reliability standards. Ensure compatibility with the 8-lead MSOP package dimensions during PCB layout. Check for any specific qualification data requests required by the procurement department.

Selection Notes

Select this component when extreme temperature stability and low offset drift are critical. The EP designation indicates enhanced reliability suitable for harsh environments. Compare the 90 µV offset limit against standard grades if cost reduction is necessary. Verify that the 400 µA supply current meets power constraints in portable or line-powered instrumentation designs.
