Overview
The ICL7653CPA is a chopper-stabilized operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features a maximum input offset voltage of 5 µV and an input bias current of 0.00001 µA at 25°C. The device operates with a nominal supply voltage of 5 V, supporting a range up to 9 V. It utilizes a 14-pin PDIP package with a lead-free plastic construction. The component provides high common-mode rejection ratio performance and maintains low drift over time and temperature.
Feature Summary
- Chopper-stabilized architecture for continuous error correction
- Extremely low input offset voltage and bias current
- Monolithic CMOS design for low power consumption
Applications
- Precision amplifier circuits
- Instrumentation amplifier designs
- Thermocouple signal conditioning
- Strain gauge interfaces
Procurement Notes
Verify the manufacturer designation as Analog Devices Inc./Maxim Integrated on official documentation. Confirm the specific suffix CPA indicates the PDIP-14 package variant. Ensure compliance with RoHS standards if required, noting that some sources indicate non-compliance for older revisions. Cross-reference the datasheet revision date to confirm parameter accuracy.
Selection Notes
Select this component for applications requiring minimal DC error without external trimming. The chopper-stabilization technique eliminates the need for offset nulling pins. Consider the 14-pin DIP package for through-hole prototyping or legacy board compatibility. Evaluate the low bias current suitability for high-impedance sensor inputs.
Part Context
This part belongs to the ICL7650/ICL7653 family of chopper-stabilized amplifiers. These devices are designed for low-level signal processing where stability and precision are critical. The family combines wide bandwidth with exceptionally low drift characteristics, making them suitable for demanding analog front-end applications in industrial and scientific instrumentation.
Replacement Considerations
The ICL7650B is documented as an improved second source to the ICL7650/53 series. Verify pinout compatibility and electrical parameter equivalence before substitution. Check for any differences in package availability or manufacturing origin between the original Maxim and alternative sources.
