ICL7612ACPA

Overview

The ICL7612ACPA+ is a single-channel, general-purpose operational amplifier manufactured by Analog Devices Inc. (Maxim Integrated). It features a CMOS architecture with a gain-bandwidth product of 1.4 MHz and a slew rate of 1.6 V/us. The device operates within a supply voltage range of 2V to 16V or ±1V to ±8V. Key electrical parameters include an input bias current of 1 pA, an input offset voltage of 15 mV, and a quiescent current of 1 mA. It utilizes an 8-PDIP through-hole package and functions within a temperature range of 0°C to +70°C.

Feature Summary

• CMOS technology enabling ultra-low input bias current for precision applications
• Wide single or dual power supply operation capability
• Rail-to-rail output swing performance

Applications

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

Procurement Notes

Verify the specific suffix 'ACPA' against official datasheets to confirm pinout and package dimensions. Confirm RoHS compliance status as indicated in the manufacturer's documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when low input bias current is critical for circuit accuracy. The CMOS input stage offers superior performance compared to bipolar alternatives in high-impedance scenarios. Ensure the required bandwidth and slew rate align with the 1.4 MHz and 1.6 V/us specifications provided in the technical data.

Part Context
