ICL7622DCPD+

Overview

The ICL7622DCPD+ is a dual operational amplifier from the ICL761X–ICL764X family, manufactured by Analog Devices Inc./Maxim Integrated. It features a monolithic CMOS design with pin-selectable quiescent currents of 10μA, 100μA, or 1000μA per amplifier. The device operates from ±1V to ±8V power supplies or single supplies from 2V to 16V. Key electrical parameters include an input bias current of 1pA typical and an input resistance of 10^12Ω. The output voltage swings to within millivolts of the supply rails. This component is housed in a 14-pin Plastic Dip package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• Ultra-low input bias current of 1pA typical for high-impedance applications
• Programmable quiescent current settings of 10μA, 100μA, or 1000μA
• CMOS outputs swing to within millivolts of supply voltages
• Industry-standard pinouts with offset null capability

Applications

• Long-time constant integrators
• Picoammeters
• Low-leakage amplifiers
• Low-frequency active filters

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature range. Confirm RoHS compliance status as indicated in the datasheet. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity. Check for any recent product change notices regarding manufacturing sites or material declarations.

Selection Notes

Select this component when ultra-low input bias current and low power consumption are critical. The programmable quiescent current allows optimization between bandwidth and power dissipation. Verify that the required gain-bandwidth product and slew rate align with the chosen IQ setting. Ensure the application environment falls within the specified commercial temperature range.

Part Context

This part belongs to the ICL761X–ICL764X series of monolithic CMOS operational amplifiers. The series combines ultra-low input current with low-power operation over a wide supply voltage range. The dual configuration (ICL7622) provides two independent amplifiers in a single package, sharing common power and ground connections while maintaining separate signal paths.

Replacement Considerations

Check for ICL7622 variants with different temperature ranges or packages. Verify compatibility with other dual op-amps offering similar bias current specifications.
