ICL7612DCPA+

Overview

The ICL7612DCPA+ is a single-channel, low-power CMOS operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features an 8-pin Plastic DIP package and operates within a temperature range of 0°C to +70°C. The device supports wide supply voltages from ±1V to ±8V or single supplies from 2V to 16V. Key electrical characteristics include a typical input bias current of 1pA, a maximum input offset voltage of 15mV, and a unity-gain bandwidth of 0.044MHz at the lowest quiescent current setting.

Feature Summary

• Ultra-low input bias current of 1pA ensures minimal loading on high-impedance signal sources.
• Monolithic CMOS design enables operation over a wide supply voltage range with rail-to-rail output swing.
• Internal offset nulling capability allows for precise adjustment of input offset voltage.

Applications

• Long-time constant integrators
• Picoammeters
• Low-leakage amplifiers

Procurement Notes

Verify the component status as discontinued through official manufacturer channels before finalizing procurement plans. Confirm that the specific ordering suffix matches the required package type and temperature rating. Ensure compliance with relevant environmental standards such as RoHS requirements applicable to the manufacturing date.

Selection Notes

Select this component when ultra-low input bias current is critical for maintaining accuracy in high-impedance circuits. The fixed quiescent current distinguishes it from other family members with programmable settings. Verify that the operating temperature range meets the system's environmental requirements.

Part Context

This part belongs to the ICL761X–ICL764X family of monolithic CMOS operational amplifiers. The family combines low power consumption with high input impedance. The ICL7612 variant specifically provides a single amplifier configuration within an 8-pin package, offering a compact solution for precision analog signal conditioning tasks.

Replacement Considerations

Consult the manufacturer's documentation for verified second-source equivalents. Cross-reference pinouts and electrical specifications to ensure functional compatibility without circuit redesign.
