AMP02FPZ

Overview

The AMP02FPZ is a precision instrumentation amplifier manufactured by Analog Devices Inc., housed in an 8-pin DIP package. It features a fixed internal gain of 100 V/V, providing high accuracy for signal conditioning applications. The device operates with a supply voltage range of ±5V to ±15V and draws a typical supply current of 3.5mA per channel. Key electrical characteristics include a low input offset voltage of 75µV maximum and a high common-mode rejection ratio (CMRR) of 96dB minimum at DC. It supports a wide common-mode voltage range and offers short-circuit protection on the outputs.

Feature Summary

• Integrated precision instrumentation amplifier architecture with fixed internal gain
• High common-mode rejection ratio ensuring accurate differential signal amplification
• Wide common-mode voltage range compatible with various sensor interfaces
• Output short-circuit protection for enhanced circuit reliability

Applications

• Precision data acquisition systems requiring isolated signal conditioning
• Industrial process control instrumentation and transducer interfaces
• Medical equipment and diagnostic devices demanding high accuracy
• Strain gauge and load cell measurement circuits

Procurement Notes

Verify the specific suffix 'FPZ' against the manufacturer's official datasheet to confirm pinout compatibility and RoHS compliance status. Ensure the required gain configuration matches the fixed internal value of 100 V/V, as external gain setting resistors are not applicable for this specific part number. Cross-reference the package dimensions with the target PCB footprint to avoid mechanical integration errors during assembly.

Selection Notes

Select the AMP02FPZ when a fixed gain of 100 V/V is sufficient for the application, eliminating the need for external precision resistors. Consider this component for designs prioritizing board space reduction and simplified biasing over adjustable gain flexibility. Evaluate the input offset voltage and drift specifications against the system's total error budget to ensure measurement accuracy requirements are met under varying temperature conditions.

Part Context

The AMP02 belongs to Analog Devices' legacy family of monolithic instrumentation amplifiers, designed to replace discrete resistor networks. It integrates matched input buffers and a precision gain stage into a single chip. This integration significantly reduces noise, drift, and component count compared to traditional three-op-amp topologies. The FPZ designation indicates a lead-free, halogen-free PDIP package compliant with modern environmental standards.

Replacement Considerations

Direct replacements include the AMP02E or AMP02K for tighter tolerance variants. For pin-compatible upgrades with improved performance, consider the AD620 series with external gain setting or the AD8221 for lower power consumption. Verify that any substitute maintains the required 8-pin DIP form factor and similar supply voltage ranges.
