AMP04ESZ

Overview

The AMP04ESZ is a precision instrumentation amplifier manufactured by Analog Devices Inc., housed in an 8-SOIC surface-mount package. It operates within a supply voltage range of 5 V to 30 V and draws a typical operating current of 700 µA. The device provides a fixed differential gain of 60 dB (1000 V/V) with a 3-dB bandwidth of 700 kHz. Key electrical characteristics include a common-mode rejection ratio of 90 dB, a power supply rejection ratio of 105 dB, and an input bias current of 30 nA. It functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides a fixed internal gain of 1000 V/V for high-precision signal conditioning
• Features low input bias current and high input impedance for minimal loading effects
• Delivers high common-mode rejection and power supply rejection ratios

Applications

• Precision data acquisition systems requiring fixed-gain amplification
• Industrial process control sensor interfaces
• Medical instrumentation signal conditioning

Procurement Notes

Verify the specific suffix 'ESZ' confirms the 8-SOIC surface-mount package variant. Confirm that the fixed gain requirement matches the internal 60 dB specification, as external resistor adjustment is not supported on this model. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range.

Selection Notes

Select this component when a fixed gain of 1000 V/V is required without external feedback resistors. It is suitable for applications needing a wide single or dual supply range up to 30 V. Consider the 700 µA quiescent current for power budgeting. Verify that the 700 kHz bandwidth meets the signal frequency requirements.

Part Context

The AMP04ESZ belongs to the AMP04 series of precision instrumentation amplifiers from Analog Devices. This family is designed for applications demanding high accuracy and stability. The ESZ designation specifically identifies the lead-free, halogen-free version packaged in the standard 8-pin SOIC format for automated surface-mount assembly.

Replacement Considerations

The AMP04FPZ serves as a through-hole replacement option within the same product family, offering identical electrical performance but in a PDIP-8 package.
