AMP01FX

Overview

The AMP01FX is a monolithic instrumentation amplifier from Analog Devices, housed in an 18-pin CDIP package. It features a gain bandwidth product of 26 MHz and a slew rate of 4.5 V/µs. The device offers a common-mode rejection ratio of 115 dB with an input bias current of 4 nA and input offset voltage of 40 µV. Operating on supply voltages between 4.5 V and 18 V, it draws 3 mA of quiescent current. The amplifier supports gains from 0.1 V/V to 10,000 V/V and maintains stability with capacitive loads up to 1 nF.

Feature Summary

• Monolithic construction designed for high-precision data acquisition
• Capacitive load stability up to 1 nF without oscillation
• Low noise performance with 0.12 µV peak-to-peak specification
• Excellent output drive capability supporting ±10 V swing

Applications

• High-precision data acquisition systems
• Industrial process control instrumentation
• Medical equipment signal conditioning
• Strain gauge and transducer interfaces

Procurement Notes

Verify the specific suffix FX against official Analog Devices documentation to confirm pinout and electrical tolerances. Ensure the procurement channel provides genuine components with traceable manufacturing dates. Check for RoHS compliance status as indicated in manufacturer records. Confirm package integrity upon receipt to prevent damage to the ceramic dual in-line structure during installation.

Selection Notes

Select this component when low offset voltage and high common-mode rejection are critical. The fixed internal architecture limits external gain adjustment options compared to programmable alternatives. Consider the 18-pin CDIP footprint for PCB layout constraints. Evaluate thermal management requirements given the operating temperature range extends to +125°C for industrial environments.

Part Context

The AMP01 series represents a family of precision instrumentation amplifiers known for their robust design and ease of use. The AMP01FX variant specifically targets applications requiring stable performance under varying common-mode conditions. It serves as a foundational building block for analog front-end circuits where signal integrity is paramount.

Replacement Considerations

Consult Analog Devices for direct replacements within the AMP01 family. Verify pin compatibility and electrical specifications before substituting. Cross-reference with other manufacturers only if form-fit-function matches are confirmed through official datasheets.
