AMP04ESZ-R7

Overview

The AMP04ESZ-R7 is a single-channel instrumentation amplifier from the Analog Devices AMP04 series, housed in an SOIC-8 surface-mount package. It features a fixed voltage gain of 60 dB (equivalent to a linear gain of 1000 V/V). Key electrical specifications include a 3dB bandwidth of 700 kHz, a common-mode rejection ratio (CMRR) of 90 dB, and a power supply rejection ratio (PSRR) of 105 dB. The device operates with input bias current of 30 nA and input offset voltage of 150 uV. It supports a supply voltage range from 5 V to 30 V, draws 700 uA of operating current, and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides fixed unity-gain-adjusted amplification with high common-mode rejection for precise signal conditioning.
• Delivers wide bandwidth performance suitable for high-speed data acquisition applications.
• Features low power consumption and rail-to-rail output capability for efficient system integration.

Applications

• Industrial process control systems requiring accurate sensor signal amplification
• Medical instrumentation equipment demanding high common-mode noise rejection
• Data acquisition systems utilizing analog-to-digital conversion interfaces

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing components. Confirm that the SOIC-8 package dimensions match the target PCB footprint requirements. Ensure the fixed gain configuration aligns with the system design without requiring external resistors. Check RoHS compliance status against current regulatory standards for the intended market.

Selection Notes

Select this component when a fixed gain of 1000 V/V is required without external resistor networks. Consider the 700 kHz bandwidth limit for signal frequency constraints. Evaluate the 150 uV input offset voltage against precision requirements. Compare power consumption against battery-operated alternatives if energy efficiency is critical.

Part Context

This part belongs to the AMP04 family of instrumentation amplifiers designed by Analog Devices. The series is characterized by its monolithic construction, which eliminates the need for external precision resistors typically found in discrete instrumentation amplifier designs. The ESZ suffix denotes the specific SOIC-8 surface-mount package variant.
