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 specifications include a unity-gain bandwidth of 2 MHz, a slew rate of 2.5 V/µs, and an input offset voltage of 10 µV maximum. The device draws 3.5 mA typical supply current and supports a supply voltage range of 4.5 V to 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 with extended common-mode voltage range
- Supports internal or external clock operation via dedicated control pins
Applications
- Condition Amplifier
- Precision Amplifier
- Instrumentation Amplifier
- Thermocouples
- Strain Gauges
Procurement Notes
Verify the specific suffix 'CSD+' against official manufacturer documentation to confirm pinout compatibility and lead-free status. Confirm that the 14-pin SOIC package matches the target PCB footprint. Ensure the commercial temperature rating aligns with system requirements before finalizing procurement.
Selection Notes
Select this component for applications requiring high DC precision and low drift without manual trimming. Consider the 14-pin version if external clocking or output clamping is required. Evaluate load driving capabilities, as open-loop gain varies with resistance. Ensure proper board guarding techniques are implemented to maintain high input impedance performance.
Part Context
This device belongs to the ICL7650 family of chopper-stabilized amplifiers, which are successors to Intersil designs. The family includes variants like the ICL7653, which lacks the clamp feature but offers slightly lower noise. These amplifiers utilize a nulling scheme where a secondary amplifier corrects the main amplifier's offset continuously.
Replacement Considerations
The ICL7650B series serves as an exact replacement for Intersil’s ICL7650B devices. Verify pin compatibility with legacy designs such as the LM741 or OP07 when adapting existing circuits.
