ICL7642CCPD+

Overview

The ICL7642CCPD+ is a quad CMOS operational amplifier from the ICL761X–ICL764X family, manufactured by Analog Devices Inc./Maxim Integrated. It features a voltage-feedback architecture in a 14-pin plastic DIP package. Key electrical parameters include a maximum average input bias current of 0.004 µA and a nominal common-mode rejection ratio of 80 dB. The device operates within supply voltages ranging from ±1V to ±8V or single supplies from 2V to 16V. It has a maximum input offset voltage of 12000 µV at 25°C.

Feature Summary

• Combines ultra-low input current with low-power operation suitable for wide supply voltage ranges.
• Features pin-selectable quiescent currents per amplifier for power optimization.
• CMOS outputs swing to within millivolts of the supply rails.

Applications

• Long time constant integrators
• Picoammeters
• Low droop rate sample/hold amplifiers

Procurement Notes

Verify component authenticity through authorized channels as this part may be discontinued. Confirm package integrity and lead condition upon receipt. Check RoHS compliance status against specific project requirements since documentation indicates non-compliance in some records. Ensure storage conditions prevent moisture damage prior to soldering.

Selection Notes

Select this component when designing circuits requiring extremely low input bias currents and rail-to-rail output capability. Consider the trade-off between higher quiescent current settings for speed versus lower settings for power efficiency. Verify that the 14-pin DIP form factor fits the target PCB layout constraints compared to surface-mount alternatives.

Part Context

This device belongs to the ICL761X–ICL764X family of monolithic CMOS op amps. The 'CCPD' suffix denotes the commercial temperature range and the 14-lead plastic dual in-line package. It serves as the quad-channel variant within this series, offering four independent amplifiers in a single integrated circuit.
