Overview
The ICL7642BCPD is a quad monolithic CMOS operational amplifier from the ICL761X–ICL764X family, manufactured by Maxim Integrated. It features ultra-low input bias current of 1pA typical and low-power operation over a wide supply voltage range of ±1V to ±8V or single supplies from 2V to 16V. The device offers pin-selectable quiescent currents for singles and triples, though this quad variant has fixed settings. Outputs swing to within millivolts of the supply rails, ensuring high dynamic range.
Feature Summary
- Ultra-low input bias current of 1pA typical
- Wide supply voltage range from ±1V to ±8V
- CMOS outputs swing to within millivolts of supply voltages
- Monolithic low-power CMOS design
Applications
- Long time constant integrators
- Picoammeters
- Low droop rate sample/hold amplifiers
- Battery-powered instruments
- Hearing aids and microphone amplifiers
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm temperature range and package type. Ensure compatibility with existing circuit designs regarding supply voltage limits and output swing characteristics. Cross-reference part numbers with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component for applications requiring minimal input bias current and low power consumption. Consider the fixed quiescent current nature of the quad configuration compared to pin-selectable options in single/dual variants. Evaluate the need for rail-to-rail output swing capabilities and wide supply voltage tolerance.
Part Context
This part belongs to the ICL761X–ICL764X family of general-purpose CMOS operational amplifiers. The '4' indicates a quad configuration containing four independent amplifiers. The 'B' suffix denotes a specific offset voltage grade, while 'CPD' specifies the plastic DIP package and commercial temperature range.
Replacement Considerations
Check for pin-compatible alternatives within the same family, such as ICL7642CCPD or ICL7642ECPD, which may offer different temperature ranges or offset voltage grades. Verify electrical specifications match application requirements before substitution.
