ICL7612BCAR2207

Overview

The ICL7612BCAR2207 is a single operational amplifier belonging to the ICL761X–ICL764X family of monolithic CMOS devices. It features ultra-low input bias current and low-power operation across a wide supply voltage range, supporting ±1V to ±8V dual supplies or 2V to 16V single supplies. The device offers pin-selectable quiescent currents of 10µA, 100µA, or 1000µA per amplifier. Its CMOS output stage swings to within millivolts of the supply rails, and it exhibits an input offset voltage maximum of 3000 µV with a bandwidth of 0.044 MHz.

Feature Summary

• Ultra-low input bias current of 1pA suitable for high-impedance circuits
• Pin-selectable quiescent current options for power optimization
• Rail-to-rail CMOS output swing capability
• Wide operating supply voltage range

Applications

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

Procurement Notes

Verify the manufacturer origin as Harris Corporation or Maxim Integrated, noting that Maxim acquired Intersil which originally produced this line. Confirm the specific suffix 'BCAR2207' corresponds to the intended package and temperature grade against official datasheets. Ensure compatibility with the standard ICL7612 electrical specifications before procurement.

Selection Notes

Select this component when designing circuits requiring minimal input current loading and low power consumption. The ability to adjust quiescent current via pins allows balancing between speed and power efficiency. Verify that the required supply voltage falls within the specified ±1V to ±8V range for optimal performance.

Part Context

This part is part of the broader ICL761X–ICL764X family of general-purpose CMOS operational amplifiers. These devices are characterized by their combination of high input impedance and low power dissipation, making them distinct from bipolar op-amps in applications sensitive to bias current.

Replacement Considerations

Check for direct replacements such as ICL7612ACPE or ICL7612ECSE if the specific suffix variant is unavailable, ensuring the package type and temperature range match the design requirements.
