AMP02EPZ

Overview

The AMP02EPZ is a precision instrumentation amplifier manufactured by Analog Devices Inc. It features a single channel with a 3dB bandwidth of 1 MHz and a slew rate of 6 V/us. The device offers a common-mode rejection ratio (CMRR) of 120 dB, an input bias current (Ib) of 5 nA, and an input offset voltage (Vos) of 50 uV. It operates on a power supply ranging from 4.5 V to 36 V, with a maximum supply voltage of 36 V. The typical operating supply current is 325 uA. It supports a minimum operating temperature of -40°C and a maximum of +85°C. The component is housed in an 8-PDIP package.

Feature Summary

• Provides high-precision signal amplification with exceptional common-mode rejection capabilities for accurate differential measurements.
• Maintains pin-for-pin compatibility with industry-standard operational amplifiers while delivering superior performance metrics.
• Features low input bias current and low offset voltage to ensure minimal signal distortion in sensitive applications.

Applications

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

Procurement Notes

Verify the specific suffix EPZ indicates the PDIP package variant when sourcing. Confirm the manufacturer is Analog Devices Inc. as part numbers may be shared across distributors. Check for RoHS compliance status if required by your manufacturing standards. Ensure the operating temperature range meets your environmental specifications before finalizing procurement.

Selection Notes

Select this component when high CMRR and low offset voltage are critical for signal integrity. It serves as a direct upgrade over standard 741-type amplifiers without requiring PCB layout changes. Consider the 1 MHz bandwidth for applications requiring moderate speed. Evaluate the 325 uA supply current against power constraints in battery-operated designs.

Part Context

The AMP02EPZ belongs to the AMP02 series of instrumentation amplifiers from Analog Devices. This series is designed to replace older general-purpose operational amplifiers like the 741 type. It integrates precision resistors internally to set gain, simplifying circuit design compared to discrete resistor networks.
