AMP04ES

Overview

The AMP04ES is a precision instrumentation amplifier manufactured by Analog Devices Inc. It features a fixed internal gain of 25 V/V, providing high accuracy for signal conditioning applications. The device operates on single or dual power supplies ranging from 5 V to 30 V. Key electrical characteristics include a low input bias current of 30 nA and an input offset voltage of 150 µV. It offers a common-mode rejection ratio of 90 dB and a power supply rejection ratio of 105 dB. The unit is housed in an 8-lead SOIC package and supports a bandwidth of 700 kHz.

Feature Summary

• Fixed internal gain configuration eliminates the need for external precision resistors.
• High common-mode rejection ratio ensures accurate differential signal amplification.
• Low input bias current minimizes loading effects on high-impedance sources.

Applications

• Precision data acquisition systems
• Industrial process control instrumentation
• Medical equipment signal conditioning

Procurement Notes

Verify the specific suffix (e.g., ESZ) against the manufacturer's official datasheet to confirm pinout compatibility and packaging type. Ensure the selected variant matches the required operating temperature range and supply voltage specifications for the target application environment.

Selection Notes

Select this component when a stable, fixed-gain instrumentation amplifier is required without external gain-setting components. Consider the 700 kHz bandwidth and 150 µV offset voltage limits relative to the signal frequency and DC accuracy requirements of the design.

Part Context

This part belongs to the AMP04 family of instrumentation amplifiers designed for general-purpose precision applications. The series is characterized by its simplicity and robust performance in industrial environments, offering a reliable alternative to discrete resistor-based amplifier designs.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified equivalents. Generic replacements may differ in gain stability, CMRR, or pin configuration; verify all parameters against the original specification sheet before substitution.
