ICL7612DCBAZ-T

Overview

The ICL7612DCBAZ-T is a single-channel, low-power CMOS operational amplifier manufactured by Renesas Electronics Corporation. It features a gain-bandwidth product of 1.4 MHz and a typical slew rate of 1.6 V/µs. The device operates within a supply voltage range of ±1V to ±8V (or 2V to 16V single supply). Key electrical characteristics include an input bias current as low as 50 pA (typical) and an input offset voltage of 15 mV. It delivers an output current of 40 mA per channel with a power consumption as low as 20 µW. The component is housed in an 8-SOIC surface-mount package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Ultra-low input bias current capability suitable for high-impedance signal sources
• Programmable power consumption allowing optimization for low-energy applications
• Wide operating voltage range supporting flexible single or dual supply configurations

Applications

• High-impedance sensor interface circuits
• Battery-powered instrumentation systems
• Low-power data acquisition front ends

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official Renesas documentation prior to integration. Ensure the SOIC-8 footprint matches the target PCB layout. Validate that the commercial temperature range meets the environmental requirements of the final assembly.

Selection Notes

Select this component for designs requiring minimal quiescent current without sacrificing moderate bandwidth. The low input bias current makes it preferable over standard BJT or JFET op-amps for capacitive sensors. Compare the 1.4 MHz bandwidth against application speed requirements. Consider the 8-SOIC package constraints for thermal management in dense layouts.

Part Context

This part belongs to the ICL7612 series of low-power CMOS operational amplifiers from Renesas. The series is characterized by its ability to operate at very low currents while maintaining stable performance across a wide voltage range. It serves as a general-purpose amplifier solution for cost-sensitive and power-constrained electronic systems.

Replacement Considerations

Check for direct pin-compatible alternatives within the Renesas portfolio that may offer updated packaging or extended temperature ranges. Verify functional equivalence regarding gain-bandwidth and bias current if substituting with other manufacturers' parts.
