ICL7652CWE

Overview

The ICL7652CWE is a zero-drift operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features a single circuit configuration housed in a 16-SOIC package. Key electrical parameters include an input offset voltage of 700 µV, a supply current of 2 mA, and an input bias current of 15 pA. The device operates with a supply voltage range from 5 V to 16 V. Performance specifications encompass a slew rate of 0.5 V/µs and a gain-bandwidth product of 450 kHz. It supports surface mount installation and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Zero-drift architecture designed for high precision applications
• Low power consumption with minimal supply current requirements
• High input impedance characteristics suitable for sensitive signal conditioning

Applications

• Precision sensor signal amplification
• Strain gauge measurement systems
• Thermocouple signal conditioning

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS3 compliance and REACH material declarations prior to integration. Check for specific manufacturing date codes if long-term reliability is critical. Ensure the 16-SOIC footprint matches the design layout exactly. Validate thermal performance within the specified 0°C to 70°C operating range.

Selection Notes

Select this component when ultra-low drift and low offset voltage are required over temperature variations. Compare against other zero-drift amplifiers based on available supply voltage ranges and package constraints. Consider the 450 kHz bandwidth limitation for high-speed applications. Evaluate the 16-SOIC package size against board space limitations.

Part Context
