ICL7652P

Overview

The ICL7652P is a precision operational amplifier manufactured by Texas Instruments, belonging to the TC7652 series. It features a single channel with a gain-bandwidth product of 400 kHz and a slew rate of 1 V/us. Key electrical specifications include an input offset voltage of 5 uV, input bias current of 100 pA, and common-mode rejection ratio of 120 dB. The device operates on supply voltages ranging from 2.5 V to 8 V or 5 V to 16 V, with a typical operating current of 3 mA. It is housed in an 8-pin PDIP package.

Feature Summary

• Low noise performance suitable for precision signal conditioning
• High common-mode rejection ratio for accurate differential amplification
• Ultra-low input bias current for high-impedance sensor interfaces

Applications

• Precision instrumentation amplifier circuits
• High-impedance transducer signal conditioning
• Low-noise audio preamplifiers
• Medical equipment signal processing
• Data acquisition system front-ends

Procurement Notes

Verify component authenticity through authorized Microchip or Texas Instruments distributors. Confirm manufacturing date codes and lot traceability against official datasheets. Ensure storage conditions comply with moisture sensitivity levels specified in the package information to prevent soldering defects during assembly.

Selection Notes

Select this component when low noise and high precision are required in single-supply applications. Compare input offset voltage and bias current requirements against alternative op-amps. Verify that the PDIP-8 package fits the PCB layout constraints. Check if the 400 kHz bandwidth meets the signal frequency requirements of the specific application design.

Part Context

This part is part of the TC7652 family of low-noise operational amplifiers originally developed by Micrel and now produced by Microchip Technology. The ICL prefix often indicates earlier Intersil branding before corporate acquisitions. The device is designed for applications requiring high accuracy and low power consumption in portable and battery-operated systems.

Replacement Considerations

Official substitutes may include other members of the TC7652 family such as TC7652CPA. Verify pin compatibility and electrical parameter equivalence before substitution. Consult manufacturer cross-reference guides for validated replacement options.
