Overview
The ICL7621BCPA+ is a dual-channel monolithic CMOS operational amplifier from the ICL761X–ICL764X family, manufactured by Analog Devices/Maxim Integrated. It features ultra-low input bias current of 50 pA maximum and low power consumption with a supply current of 15 µA per amplifier. The device operates on wide supply voltages ranging from ±1V to ±8V or single supplies from 2V to 16V. It includes offset null capability and fixed quiescent current settings.
Feature Summary
- Ultra-low input bias current for high-impedance source applications
- Low-power CMOS design suitable for battery-powered instruments
- Offset nulling capability via external potentiometer connection
- Rail-to-rail output swing approaching supply voltage limits
Applications
- Long-time constant integrators
- Picoammeters
- Low-leakage amplifiers
- Low-frequency active filters
Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and package integrity upon receipt. Ensure storage conditions meet specified temperature ranges to maintain electrical characteristics. Check datasheet revisions for any parameter updates before final integration into designs.
Selection Notes
Select this part when ultra-low input bias current is critical for signal integrity in high-impedance circuits. The dual configuration allows cost-effective implementation of differential stages. Verify that the fixed quiescent current meets bandwidth requirements without excessive power draw. Consider thermal management within the commercial operating range during PCB layout.
Part Context
This component belongs to the ICL76XX series of precision operational amplifiers known for their CMOS construction and low power characteristics. The 'B' suffix indicates a specific input offset voltage grade, while 'PA+' denotes an 8-pin plastic DIP package with lead-free composition. It serves as a general-purpose low-power amplifier within the broader Maxim Integrated portfolio.
Replacement Considerations
Direct pin-compatible alternatives include other members of the ICL7621 family such as ICL7621ACPA+ or ICL7621DCPA+, differing primarily in offset voltage specifications and temperature ranges. Cross-reference exact electrical parameters like Vos and Ibias before substitution.
