ICL7611DCPA

Overview

The ICL7611DCPA is a single-channel CMOS operational amplifier manufactured by Renesas Electronics Corporation. It features a gain-bandwidth product of 1.4 MHz and a slew rate of 1.6 V/µs. The device operates with an input bias current of 50 pA and an input offset voltage of 15 mV. Supply voltage ranges from 2 V to 16 V, with a typical supply current of 1 mA per channel. It provides an output current of 40 mA per channel and maintains a common-mode rejection ratio of 70 dB. The component is housed in an SOIC-8 surface-mount package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• CMOS architecture enabling low power consumption and high input impedance
• Single-channel configuration optimized for general-purpose signal processing
• Surface-mount SOIC-8 packaging for compact circuit integration

Applications

• General-purpose analog signal conditioning circuits
• Low-power sensor interface applications
• Battery-operated instrumentation systems

Procurement Notes

Verify the specific manufacturer designation on the datasheet, as the ICL7611 series has been produced by multiple vendors including Maxim Integrated and Analog Devices. Confirm that the SOIC-8 package matches your PCB footprint requirements. Ensure the commercial temperature grade (0°C to +70°C) aligns with your system's environmental specifications before finalizing procurement.

Selection Notes

Select this component when a single-channel op-amp with moderate bandwidth and low quiescent current is required. The CMOS technology offers a favorable balance between speed and power efficiency. Verify that the 40 mA output drive capability meets load requirements. Consider alternative packages if through-hole mounting is necessary, as this part number specifies surface-mount installation.

Part Context

This component belongs to the ICL7611 family of operational amplifiers. The 'D' suffix typically denotes the commercial temperature range, while 'CPA' indicates the specific package and lead finish variant. This series is designed for applications requiring low power operation without sacrificing significant performance metrics compared to standard bipolar counterparts.

Replacement Considerations

Direct substitutes include the ICL7611DCSA+ and ICL7611DCBAZ-T. These alternatives share identical electrical characteristics and pinouts but may differ in package style or manufacturing origin. Verify compatibility with existing board layouts and thermal management strategies.
