ICL7612ACSA-T

Overview

The ICL7612ACSA-T is a single-channel monolithic CMOS operational amplifier from the ICL761X–ICL764X family, manufactured by Analog Devices Inc./Maxim Integrated. It features an input bias current of 50 pA maximum and an input offset voltage of 5 mV typical at +25°C. The device operates on supply voltages ranging from ±1V to ±8V or single supplies from 2V to 16V. It utilizes an 8-pin SO package and supports a commercial temperature range of 0°C to +70°C.

Feature Summary

• Monolithic low-power CMOS design with ultra-low input bias current
• Wide supply voltage operation capability
• CMOS outputs swing to within millivolts of supply rails

Applications

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

Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm tape-and-reel packaging requirements. Ensure the AC grade designation matches the required offset voltage specifications for your application. Cross-reference the manufacturer's latest datasheet revision to confirm pinout compatibility and absolute maximum ratings before finalizing procurement orders.

Selection Notes

Select this component when extremely low input bias currents are critical for maintaining signal integrity in high-impedance circuits. The AC grade offers a tighter input offset voltage specification compared to higher grades. Consider the extended common-mode voltage range unique to the ICL7612 variant if input signals approach the negative supply rail.

Part Context

This part belongs to the ICL761X–ICL764X family of general-purpose operational amplifiers. These devices are designed for applications requiring high input impedance and low power consumption. The ICL7612 specifically provides extended common-mode voltage range capabilities not available in other members of the series.

Replacement Considerations

Check for ICL7612BCSA+T or ICL7612DCSA+T if different temperature ranges or offset voltage grades are needed. Verify pin-for-pin compatibility with other industry-standard CMOS op-amps if sourcing from alternative suppliers.
