ICL7650SCBA-1ZT

Overview

The ICL7650SCBA-1ZT is a super chopper-stabilized operational amplifier manufactured by Renesas Electronics. It features a single channel with a gain-bandwidth product of 2 MHz and a slew rate of 2.5 V/µs. The device operates within a supply voltage range of 4.5 V to 16 V, consuming 3 mA of quiescent current. It provides an input offset voltage of 5 µV and an input bias current of 10 pA. The component utilizes an SOIC-8 surface-mount package and supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Super chopper stabilization technology ensures exceptionally low input offset voltage and minimal drift over time and temperature variations.
• Extremely high common-mode rejection ratio and power supply rejection ratio provide superior noise immunity and signal integrity.
• Integrated clamp circuit prevents overload recovery issues, enabling stable operation in comparator applications.

Applications

• Precision sensor signal conditioning
• High-impedance measurement circuits
• Low-drift instrumentation amplifiers

Procurement Notes

Verify the specific suffix '1ZT' against official Renesas documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering part number matches the exact manufacturer designation to avoid discrepancies in lead times or component specifications during procurement.

Selection Notes

Select this component for applications requiring ultra-low offset voltage stability without external trimming. It serves as a direct replacement for standard ICL7650 devices while offering improved bias current and wider common-mode voltage ranges. Verify that the SOIC-8 footprint aligns with the target PCB design constraints.
