Overview
The ICL7612BCBAR2207 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 over 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. Key electrical parameters include a maximum input offset voltage of 3000 µV, a bandwidth of 0.044 MHz, and a slew rate of 0.016 V/µs. It operates from 0°C to 70°C in an 8-pin plastic DIP package.
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 capability with millivolt swing proximity
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 corporate acquisitions. Confirm the suffix BAR2207 corresponds to specific tape-and-reel packaging or lot codes rather than functional changes. Ensure the BC grade matches the required offset voltage specifications. Cross-reference the 8-pin PDIP package dimensions against standard footprint requirements.
Selection Notes
Select this component when ultra-low input bias current is critical for signal integrity. The pin-selectable quiescent current allows balancing between power consumption and performance. Verify that the 0.044 MHz bandwidth meets the application's frequency response needs. Ensure the operating temperature range of 0°C to 70°C aligns with the environmental conditions.
Part Context
This part belongs to the ICL761X series of general-purpose CMOS operational amplifiers. The series includes single, dual, triple, and quad variants sharing similar electrical characteristics. The ICL7612 specifically denotes the single amplifier configuration within this family, designed for applications requiring low power and high input impedance.
Replacement Considerations
Direct substitutes include other members of the ICL761X family such as the ICL7611 or ICL7612EMPA, provided pin compatibility and electrical parameters match. Verify that alternative packages maintain the same pinout and thermal characteristics.
