ADA4528-2TCPZ-EPR7

Overview

The ADA4528-2TCPZ-EPR7 is a dual-channel, zero-drift operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply of 2.2 V to 5.5 V or dual supplies of ±1.1 V to ±2.75 V. The device offers an offset voltage of 2.5 µV maximum and drift of 0.015 µV/°C maximum. Key electrical parameters include a unity-gain crossover frequency of 4 MHz, a gain bandwidth product of 3.4 MHz at AV = +100, and a −3 dB closed-loop bandwidth of 6.5 MHz. Supply current per amplifier is 1.5 mA typical at 5 V.

Feature Summary

• Zero-drift architecture ensures ultralow offset voltage and minimal drift over temperature variations.
• Rail-to-rail input and output swing allows operation across the full supply voltage range.
• Enhanced Product (EP) qualification supports defense and aerospace applications under AQEC standards.
• Extended industrial temperature range enables reliable performance from −55°C to +125°C.

Applications

• Thermocouples and thermopiles
• Load cell and bridge transducers
• Precision instrumentation
• Electronic scales
• Medical instrumentation

Procurement Notes

Verify that the specific ordering suffix EPR7 corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the Enhanced Product (EP) designation meets all necessary quality assurance and traceability requirements for your specific application environment before finalizing procurement.

Selection Notes

Select this component when high DC precision and low noise are critical for amplifying low-level signals. The dual-channel configuration provides two independent amplifiers in a compact package. Ensure the design accommodates the extended temperature range and enhanced reliability features required for robust industrial or aerospace environments.
