Overview
The ICL7641BMJD/HR is a quad monolithic CMOS operational amplifier from the ICL761X–ICL764X family. It features an input offset voltage of 5mV and operates within a supply voltage range of ±1V to ±8V or single supplies from 2V to 16V. The device provides pin-selectable quiescent currents of 10µA, 100µA, or 1000µA per amplifier. It exhibits ultra-low bias current characteristics with a typical value of 1pA at +25°C. The component is housed in a 14-pin CERDIP package and supports an operating temperature range of -55°C to +125°C.
Feature Summary
- Monolithic low-power CMOS design with industry-standard pinouts
- Ultra-low input bias current for high source impedance applications
- Pin-selectable quiescent current settings for performance optimization
- Rail-to-rail output swing capability approaching supply voltages
Applications
- Long-time constant integrators
- Picoammeters
- Low droop rate sample/hold amplifiers
- Battery-powered instruments
- Photodiode amplifiers
Procurement Notes
Verify the specific suffix JD/HR against official manufacturer documentation to confirm the exact package type and environmental rating. Confirm availability status as this part number may be discontinued or subject to limited production runs. Ensure compatibility with existing PCB footprints for the 14-pin ceramic dual in-line package before procurement.
Selection Notes
Select this component when extremely low input bias current is critical for signal integrity. The BM grade specifies a maximum input offset voltage of 5mV. Consider the programmable quiescent current feature to balance power consumption against bandwidth requirements. Verify that the 14-pin CERDIP package meets the thermal and mechanical constraints of the target enclosure.
Part Context
This device belongs to the ICL761X–ICL764X series of single, dual, triple, and quad operational amplifiers manufactured by Analog Devices Inc./Maxim Integrated. The series is characterized by its CMOS architecture which enables very low power operation combined with high input impedance. The quad configuration integrates four independent amplifiers into a single package.
Replacement Considerations
Consult official datasheets for pin-compatible second sources within the same family. Verify electrical parameters such as offset voltage and bias current match the original specifications.
