ICL7612DCBA-T

Overview

The ICL7612DCBA-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 within a supply voltage range of 2 V to 16 V, with a maximum dual supply of 8 V. Key electrical characteristics include an input bias current of 50 pA, an input offset voltage of 15 mV, and a quiescent current of 1 mA. It provides a common-mode rejection ratio of 70 dB and an input voltage noise density of 100 nV/sqrt Hz. The component is housed in an SOIC-8 surface-mount package and functions as a general-purpose amplifier.

Feature Summary

• CMOS architecture designed for low power consumption applications
• Low input bias current suitable for high-impedance signal sources
• General-purpose performance with rail-to-rail output capability

Applications

• Battery-powered instrumentation circuits
• Signal conditioning for sensor interfaces
• Active filtering in data acquisition systems

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm RoHS compliance status through official Renesas documentation, as historical variants may differ. Ensure the manufacturer designation matches current Renesas Electronics branding following corporate acquisitions. Validate that the SOIC-8 footprint aligns with target PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a balance between low power consumption and moderate bandwidth is required. The 1.4 MHz gain-bandwidth product supports applications needing faster response than ultra-low-power alternatives while maintaining efficiency. Consider the 50 pA input bias current for interfacing with high-impedance sensors. Verify that the 1 mA supply current fits within the system's thermal and power budget constraints compared to lower-current options.

Part Context

This part belongs to the ICL7612 series of CMOS operational amplifiers. The series is characterized by its ability to operate from a single supply or split supplies. The DCBA variant specifically denotes the industrial temperature range and SOIC-8 surface-mount package. This family serves as a modern replacement for older bipolar op-amps in portable and battery-operated designs.
