ICL7611DCPAZ

Overview

The ICL7611DCPAZ is a single-channel 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 within a supply voltage range of 2 V to 16 V, with a typical operating current of 1 mA. Key electrical specifications include an input offset voltage of 15 mV, input bias current of 50 pA, and output current capability of 40 mA. It provides a common-mode rejection ratio of 70 dB and power supply rejection ratio of 80 dB. The component is housed in an 8-pin PDIP package and supports commercial temperature operation from 0°C to +70°C.

Feature Summary

• CMOS architecture enabling low power consumption and high input impedance
• Rail-to-rail output swing capability for maximum dynamic range
• Low input bias current suitable for high-impedance sensor interfaces

Applications

• Battery-powered instrumentation circuits
• Active filter designs requiring low quiescent current
• Signal conditioning for transducer outputs

Procurement Notes

Verify the manufacturer marking on the component body to confirm it reads Renesas or Intersil, as this part was previously produced by Maxim Integrated. Ensure the suffix 'Z' indicates RoHS compliance. Cross-reference the datasheet revision date with your design requirements to ensure parameter consistency, particularly regarding input bias current and offset voltage tolerances across different production batches.

Selection Notes

Select this component when a general-purpose op amp with rail-to-rail output is required alongside low power consumption. It serves as a direct pin-compatible alternative to the ICL7612 series for single-channel applications. Consider the 1.4 MHz bandwidth limit for signal frequency requirements. The PDIP-8 package is suitable for through-hole prototyping or manufacturing environments where surface mount technology is not utilized.

Part Context

This device belongs to the ICL761x family of CMOS operational amplifiers known for their micropower characteristics. The ICL7611 variant specifically provides a single amplifier channel, distinguishing it from the dual-channel ICL7612. The component represents the transition of the legacy Maxim/Intersil product line to Renesas Electronics, maintaining identical functional specifications and pinouts for seamless integration into existing designs.
