ICL7612BCPA

Overview

The ICL7612BCPA is a single-channel, general-purpose operational amplifier manufactured by Renesas Electronics Corporation. It features a gain-bandwidth product of 1.4 MHz and a slew rate of 1.6 V/µs. The device operates on supply voltages ranging from 2 V to 16 V with a typical operating current of 1 mA. Key electrical specifications include an input offset voltage of 15 mV, an input bias current of 1 pA, and a common-mode rejection ratio of 70 dB. It provides a maximum output current of 40 mA per channel and has an input voltage noise density of 100 nV/sqrt Hz. The component is housed in an 8-DIP package and supports rail-to-rail output swing.

Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm if the Z suffix variant (ICL7612BCPZ) or equivalent active series members are available as direct replacements. Ensure compatibility with existing PCB footprints and thermal requirements when sourcing substitutes.

Selection Notes

Select this component for designs requiring low power operation with moderate bandwidth. The 1.4 MHz gain-bandwidth product suits audio and low-frequency signal processing. Consider the 8-DIP package for prototyping or through-hole manufacturing needs. Evaluate input offset voltage requirements against the 15 mV specification.

Part Context

This device belongs to the ICL761x-ICL764x series of low-power CMOS operational amplifiers. The series is characterized by high input impedance and low quiescent current. The ICL7612BCPA specifically denotes the single-channel variant within this family, offering a balance between performance and power efficiency for standard analog applications.

Replacement Considerations

Public data confirms ICL7611DCPAZ as a substitute option. Verify pinout compatibility and electrical parameter alignment before integration.
