Intersil ICL7611BCPA CMOS Operational Amplifier DIP-8 2-Piece Lot
Full Description & History
Intersil ICL7611BCPA low-power CMOS operational amplifier integrated circuits in 8-pin DIP through-hole packages. Designed for analog signal processing, high-impedance circuits, instrumentation, active filters, and electronic equipment repair. Features low input bias current, programmable quiescent current, and low power consumption.
LIFECYCLE: OBSOLETE
HISTORICAL BACKGROUND:
The ICL7611 is part of the Intersil ICL761X family of CMOS operational amplifiers developed for applications requiring high input impedance and reduced power consumption. These devices were widely used in analog instrumentation, portable measuring equipment, signal conditioning, and electronic control systems. The ICL7611BCPA is an obsolete legacy component suitable for maintaining and restoring equipment originally designed around this device.

COMPATIBILITY:
Direct replacement for equipment originally fitted with the Intersil ICL7611BCPA 8-pin DIP CMOS operational amplifier. Suitable for restoration and servicing of vintage electronic instrumentation, battery-powered measuring equipment, high-impedance sensor circuits, analog signal conditioning boards, precision integrators, sample-and-hold circuits, low-frequency active filters, picoammeters, photodiode amplifiers, and electronic control systems.
Related devices include the ICL7611BCPA+, ICL7611DCPA, ICL7612, and other ICL761X family operational amplifiers. These devices may offer replacement possibilities depending on the circuit configuration, compensation requirements, electrical characteristics, and operating conditions. They are not universally interchangeable.
Designed for circuits requiring ultra-low input bias current, programmable quiescent current, and single-supply operation from 2V to 16V or dual supplies from ±1V to ±8V. Particularly useful when preserving original circuit designs in discontinued laboratory instruments and legacy electronic equipment.
