ICL7650CSD

Overview

The ICL7650CSD is a chopper-stabilized operational amplifier manufactured by Analog Devices/Maxim Integrated. It features a 14-pin SOIC package and operates within a commercial temperature range of 0°C to +70°C. Key electrical parameters include a unity-gain bandwidth of 2 MHz, a slew rate of 2.5 V/µs, and a maximum input offset voltage of 10 µV. The device draws a typical supply current of 3.5 mA with a maximum operating supply voltage of 16 V.

Feature Summary

• Chopper-stabilized architecture providing continuous error correction for minimal drift over time and temperature
• Integrated output voltage clamp circuit designed to minimize overload recovery time
• Monolithic low-power CMOS design eliminating the need for external offset voltage trimming

Applications

• Precision Amplifier
• Instrumentation Amplifier
• Thermocouples
• Strain Gauges

Procurement Notes

Verify that the specific part number matches the required pin configuration and package type. Confirm the temperature grade aligns with system requirements. Check for obsolescence status as this component family may have limited availability from original manufacturers.

Selection Notes

Select this component for applications requiring high DC precision and low drift without manual calibration. Consider the internal clock frequency when selecting external nulling capacitors. Ensure load resistance meets minimum thresholds for optimal AC performance.

Part Context

This device belongs to the ICL7650 series of chopper-stabilized amplifiers. It serves as an improved second source to Intersil's ICL7650B. The 14-pin version distinguishes itself by offering both internal and external clock options alongside the overload protection feature.
