ICL7611ACPA

Overview

The ICL7611ACPA is a single-channel, low-power operational amplifier manufactured by Harris Corporation. It features a gain-bandwidth product of 44 kHz and a slew rate of 16 mV/us. The device operates with an input offset voltage of 2 mV and an input bias current of 50 pA. Supply voltage ranges from 1 V to 8 V or 2 V to 16 V depending on configuration. It consumes 15 uA of operating current and offers a common-mode rejection ratio of 66 dB. The component utilizes a PDIP-8 through-hole package and functions within a commercial temperature range of 0°C to +70°C.

Procurement Notes

Verify the manufacturer origin carefully as the part number history involves multiple entities including Maxim Integrated and Analog Devices. Confirm the specific suffix 'ACPA' matches the required package and temperature grade. Check current availability status as legacy components may have limited supply chains or require alternative sourcing strategies.

Selection Notes

Select this component when low quiescent current and moderate bandwidth are required. Ensure the supply voltage constraints align with the system design. Consider the PDIP-8 package size for PCB layout compatibility. Verify that the input offset voltage specifications meet the precision requirements of the target application.

Part Context

This operational amplifier belongs to the ICL7611 series, originally developed by Intersil and later acquired by Maxim Integrated, now part of Analog Devices. The series is known for its CMOS construction which provides high input impedance and low power usage compared to bipolar counterparts.
