ICL7611DCBA-T

Overview

The ICL7611DCBA-T is a single-channel CMOS operational amplifier manufactured by Renesas Electronics. It features a gain-bandwidth product of 1.4 MHz and a slew rate of 1.6 V/us. The device operates with an input bias current of 50 pA and an input offset voltage of 15 mV. It supports supply voltages ranging from 1 V to 8 V or 2 V to 16 V, consuming 1 mA of operating current. The output can source 40 mA per channel with a common-mode rejection ratio of 70 dB. It is housed in an SOIC-8 package.

Feature Summary

• CMOS architecture providing ultra-low input bias current for high impedance applications
• Wide single-supply operation capability supporting low voltage systems
• Rail-to-rail output swing allowing signal proximity to supply rails

Applications

• Low power instrumentation circuits
• Battery operated measurement devices
• High impedance sensor interfaces

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration as distinct from tube variants. Confirm manufacturer designation aligns with Renesas Electronics rather than legacy Intersil or Maxim Integrated sources. Ensure RoHS compliance documentation matches the current production batch requirements for your assembly process.

Selection Notes

Select this component when low quiescent current and wide supply range are required alongside moderate bandwidth. Compare against other ICL761X family members if different pin-selectable bias currents are needed. Verify that the 1.4 MHz gain-bandwidth product meets the signal frequency requirements of the target application design.

Part Context

This part belongs to the ICL761X series of monolithic CMOS operational amplifiers. The series combines ultra-low input current with low-power operation over a wide supply voltage range. These devices are designed for applications requiring minimal power consumption while maintaining stable performance across varying supply conditions.

Replacement Considerations

Check for ICL7611DCSA+ from Analog Devices/Maxim Integrated which shares similar electrical characteristics but may differ in package availability.
