Overview
The ICL7650CPA+ is a chopper-stabilized operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5V to 16V and functions across a commercial temperature range of 0°C to +70°C. The device features a unity-gain bandwidth of 2.0MHz, a slew rate of 2.5V/µs, and an input offset voltage of ±10µV. It utilizes a monolithic low-power CMOS design with a typical supply current of 2.0mA.
Feature Summary
- Chopper-stabilized architecture providing continuous error correction for minimal drift over time and temperature
- Monolithic low-power CMOS design ensuring high performance and versatility in signal processing
- Integrated output clamp circuit on the ICL7650 variant to minimize overload recovery time
Applications
- Condition Amplifier
- Precision Amplifier
- Instrumentation Amplifier
- Thermocouples
- Strain Gauges
Procurement Notes
Verify that the component matches the specific ICL7650CPA+ designation to ensure correct package type and temperature rating. Confirm authenticity through authorized distributors or official manufacturer channels. Check datasheet specifications against application requirements before procurement to avoid compatibility issues.
Selection Notes
Select this component for applications requiring extremely low DC offset and drift without manual trimming. Consider the ICL7653 if the output clamp feature is unnecessary, as it offers slightly lower noise. Ensure external nulling capacitors are selected for low leakage and dielectric absorption to maintain optimal settling times.
Part Context
This part belongs to the ICL7650/ICL7653 family of chopper-stabilized amplifiers. It serves as an improved second source to Intersil's ICL7650B/ICL7653B. The device combines low input bias current with wide bandwidth, making it suitable for precision analog signal conditioning tasks where stability is critical.
Replacement Considerations
The ICL7650BCPA is documented as an exact replacement for Intersil’s ICL7650B. Verify pinout compatibility when substituting standard op-amps like the LM741, as external nulling connections differ from traditional offset null configurations.
