Overview
The ICL7611DC/D is a single-channel monolithic CMOS operational amplifier from the ICL761X–ICL764X family. It features an input bias current of 50 pA maximum and an input offset voltage of 15 mV maximum at +25°C. The device operates on dual supplies ranging from ±1 V to ±8 V or single supplies from 2 V to 16 V. Key electrical parameters include a unity-gain bandwidth of 44 kHz, a slew rate of 16 mV/µs, and an input resistance of 10^12 Ω. It utilizes an 8-pin SOIC package.
Feature Summary
- Monolithic low-power CMOS design with ultra-low input bias current
- Wide supply voltage range supporting both dual and single power sources
- Rail-to-rail output swing capability approaching supply voltages
Applications
- Long time constant integrators
- Picoammeters
- Low-leakage amplifiers
- Low-frequency active filters
Procurement Notes
Verify the specific suffix 'D' for the 15 mV offset voltage grade and '/D' for the industrial temperature range against the manufacturer's official ordering information. Confirm that the package designation matches the required surface-mount footprint. Ensure compatibility with the intended supply voltage constraints before finalizing procurement.
Selection Notes
Select this component when extremely low input bias currents are critical for signal integrity. The fixed quiescent current setting limits programmability compared to other family members. Evaluate the trade-off between the specified 44 kHz bandwidth and the low power consumption requirements of the target circuit design.
Part Context
This part belongs to the ICL761X–ICL764X series of precision operational amplifiers manufactured by Analog Devices / Maxim Integrated. The series is characterized by its CMOS architecture which enables high input impedance and low power operation suitable for battery-powered instrumentation and high-impedance sensor interfaces.
Replacement Considerations
Direct pin-for-pin second source equivalents exist within the same product family. Verify that any substitute maintains the required 15 mV offset voltage specification and the 8-pin SOIC physical dimensions.
