Overview
The ICL7611BCSA+ is a single-channel monolithic CMOS operational amplifier manufactured by Analog Devices/Maxim Integrated. It features an input bias current of 50 pA maximum and an input offset voltage of 5 mV typical at +25°C. The device operates from ±1V to ±8V dual supplies or 2V to 16V single supplies, with a unity-gain bandwidth of 44 kHz and a slew rate of 16 mV/us. It utilizes an 8-pin SOIC package and supports a commercial operating temperature range of 0°C to +70°C.
Feature Summary
- Ultra-low input bias current for high-impedance source applications
- Pin-selectable quiescent current settings for power-performance optimization
- Rail-to-rail output swing capability approaching supply voltages
Applications
- Long time constant integrators
- Picoammeters
- Low droop rate sample/hold amplifiers
- pH meters and photodiode amplifiers
Procurement Notes
Verify the specific suffix 'BCSA+' against official manufacturer documentation to confirm the exact electrical grade (B), temperature range (C), and package type (SOIC). Ensure compatibility with existing PCB footprints and thermal management requirements for the 8-pin small outline configuration before finalizing procurement.
Selection Notes
Select this component when ultra-low input bias current is critical for signal integrity in high-impedance circuits. The B-grade specification offers tighter offset voltage tolerances compared to standard grades. Consider the programmable quiescent current feature if dynamic power consumption needs to be balanced against bandwidth requirements.
Part Context
This part belongs to the ICL761X–ICL764X family of low-power CMOS operational amplifiers. The family combines ultra-low input current with wide supply voltage operation. The ICL7611 variant specifically provides a single amplifier channel within this architecture, designed for precision analog signal conditioning tasks requiring minimal input loading.
Replacement Considerations
The datasheet identifies the device as having a pin-for-pin second source option. Verify equivalent part numbers from authorized distributors that match the ICL7611BCSA+ specifications and package dimensions.
