ICL7622DCJD

Overview

The ICL7622DCJD is a dual, low-power CMOS operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features pin-selectable quiescent current options of 10 µA, 100 µA, or 1 mA per amplifier to optimize power consumption for specific applications. The device operates with a supply voltage range up to 9 V and provides rail-to-rail output swing. It is housed in a 14-CDIP package and is designed for commercial temperature ranges.

Feature Summary

• Dual low-power CMOS architecture
• Pin-selectable quiescent current configuration
• Rail-to-rail output capability

Applications

• Battery-powered instrumentation
• Portable consumer electronics
• Low-power signal conditioning circuits

Procurement Notes

Verify the specific manufacturer source, as Maxim Integrated products are now part of Analog Devices Inc. Confirm the package type matches the required footprint, as variations such as DIP or SOIC may exist within the ICL7622 family. Ensure the selected variant supports the necessary quiescent current settings via pin selection for the target design.

Selection Notes

Select this component when dual op-amps with adjustable power consumption are required. The pin-selectable quiescent current allows designers to balance speed and power efficiency. Verify that the rail-to-rail output meets the load requirements and that the commercial temperature range is sufficient for the operating environment.

Part Context

The ICL7622 series includes single, dual, triple, and quad variants of low-power CMOS operational amplifiers. The DCJD designation specifically refers to the dual amplifier version in a 14-pin ceramic dual in-line package (CDIP). This family is known for its flexibility in power management through hardware configuration.

Replacement Considerations

Direct substitutes include other dual low-power CMOS op-amps from the same manufacturer family, such as the ICL7622DCSD or ICL7622DCPD, provided the package type and pinout compatibility are verified.
