Overview
The ICL7621BESA+T is a dual-channel monolithic CMOS operational amplifier from the ICL761X–ICL764X family. It features ultra-low input bias current of 1pA typical and low-power operation across a wide supply voltage range of ±1V to ±8V or single supplies from 2V to 16V. The device offers rail-to-rail output swing, internally compensated for unity-gain stability, and fixed quiescent currents. It is housed in an 8-pin SO package with an industrial temperature range of -40°C to +85°C.
Feature Summary
- Ultra-low input bias current of 1pA typical
- Wide supply voltage range from ±1V to ±8V
- Rail-to-rail output voltage swing capability
- Internally compensated for unity-gain stability
Applications
- Long time constant integrators
- Picoammeters
- Low droop rate sample/hold amplifiers
- pH meters
- Photodiode amplifiers
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm exact electrical grades, temperature ranges, and packaging specifications. Confirm RoHS compliance status and ensure compatibility with existing PCB footprints before procurement.
Selection Notes
Select this component when applications require extremely low input bias currents and high source impedance handling. Consider the fixed quiescent current settings inherent to the dual configuration versus programmable options available in single-channel variants within the same family.
Part Context
This part belongs to the ICL761X–ICL764X series of general-purpose CMOS operational amplifiers manufactured by Analog Devices / Maxim Integrated. The series combines low power consumption with high input impedance, making it suitable for precision analog signal conditioning tasks requiring minimal loading on high-impedance sources.
Replacement Considerations
Check for pin-compatible alternatives within the ICL7621 family such as ICL7621DESA+ for extended temperature ranges or different offset voltage grades. Verify that substitute parts maintain identical quiescent current characteristics and compensation requirements.
