ICL7614BCTV-2

Overview

The ICL7614BCTV-2 is a single-channel CMOS operational amplifier from the ICL761X–ICL764X family, manufactured by Analog Devices Inc./Maxim Integrated. It features ultra-low input bias current and low-power operation over a wide supply voltage range. The device operates from ±1V to ±8V dual supplies or 2V to 16V single supplies. Key electrical parameters include a gain-bandwidth product of 44 kHz, a slew rate of 16 mV/µs, an input offset voltage of 3000 µV (3 mV), and an input bias current of 50 pA. The quiescent current is typically 15 µA. It is housed in an 8-pin TO-99 metal can package.

Feature Summary

• Ultra-low input bias current for high source impedance applications
• Low-power CMOS design with programmable quiescent current options
• Wide supply voltage range compatibility
• CMOS output swing near supply rails

Applications

• Long time constant integrators
• Picoammeters
• Low droop rate sample/hold amplifiers
• pH meters
• Photodiode amplifiers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance requirements as historical data indicates non-compliant variants exist. Ensure the TO-99-8 package matches the target PCB footprint. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this component when ultra-low input bias current is critical for signal integrity. It is suitable for battery-powered instruments requiring minimal power consumption. Consider the TO-99-8 package constraints for space-limited designs. Evaluate the 44 kHz bandwidth against application frequency requirements. Compare against other ICL761X family members for pin-compatible alternatives if different channel counts are needed.

Part Context

This part belongs to the ICL761X–ICL764X family of monolithic CMOS operational amplifiers. The family combines ultra-low input current with low-power operation. These amplifiers are designed for applications where input bias and offset currents are critical factors. The ICL7614 variant specifically offers a single amplifier configuration within this series.

Replacement Considerations

Check for pin-for-pin second sources within the ICL761X–ICL764X family. Verify equivalent specifications for bias current, supply voltage range, and package type. Consult official substitution guides for confirmed compatible replacements.
