ICL7641ECPD

Overview

The ICL7641ECPD is a quad monolithic CMOS operational amplifier from the ICL76XX family, housed in a 14-pin plastic DIP package. It features ultra-low input bias current of 1pA typical and low power consumption with fixed quiescent current settings. The device operates on dual supplies ranging from ±1V to ±8V or single supplies from 2V to 16V. Key electrical characteristics include a unity-gain bandwidth of 0.044MHz at 10μA per amplifier, an input offset voltage maximum of 20mV, and rail-to-rail output swing capability.

Feature Summary

Ultra-low input bias current suitable for high-impedance sources
Wide supply voltage range operation
Rail-to-rail output voltage swing
Low power CMOS design

Applications

Long time constant integrators
Picoammeters
Low droop rate sample/hold amplifiers
pH meters
Photodiode amplifiers

Procurement Notes

Verify the specific suffix ECPD corresponds to the 14-pin Plastic DIP package and C series temperature range (0°C to +70°C). Confirm that the quad configuration matches the required circuit count. Check for lead-free compliance status if RoHS is mandatory for the assembly process. Ensure the manufacturer source is recognized as Analog Devices or Maxim Integrated.

Selection Notes

Select this component when multiple low-bias channels are required in a single package. The fixed quiescent current simplifies design compared to single-channel variants. Verify that the 0.044MHz bandwidth meets the signal frequency requirements. Consider the 20mV offset voltage limit for precision applications requiring minimal calibration.

Part Context

This part belongs to the ICL761X–ICL764X family of monolithic CMOS op amps. The '4' indicates a quad configuration containing four independent amplifiers. The 'E' denotes the input offset voltage grade, and 'CPD' specifies the 14-pin plastic DIP package with commercial temperature range. It shares pinouts with other family members for flexibility.
