ISL28230CBZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28230CBZ-T7A is a dual-channel micro-power operational amplifier manufactured by Renesas Electronics Corporation. It features zero-drift architecture with rail-to-rail input and output capabilities, operating on a single supply voltage ranging from 1.8 V to 5.5 V. The device draws only 20 µA of supply current per two channels and delivers 15 mA of output current per channel. Key electrical specifications include a gain-bandwidth product of 400 kHz, a slew rate of 0.2 V/µs, an input offset voltage of 5 µV, and an input bias current of 250 pA. It is housed in an 8-SOIC package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Zero-drift technology ensures minimal input offset voltage drift over temperature variations.
• Rail-to-rail input and output operation maximizes dynamic range at low supply voltages.
• Ultra-low power consumption enables extended battery life in portable applications.

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered sensor interfaces
• Precision data acquisition systems

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'T7A' against official Renesas documentation, as standard listings often show 'CBZ'. Confirm RoHS3 compliance status and check for End-of-Life notices or Product Change Notices regarding packaging or manufacturing site updates before finalizing procurement plans.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low quiescent current and high precision are required in space-constrained designs. Compare the 8-SOIC package dimensions against PCB layout constraints. Ensure the 400 kHz bandwidth meets signal frequency requirements and that the 15 mA output drive capability suffices for the load impedance.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28x30 series of zero-drift amplifiers. It shares core electrical characteristics with variants like the ISL28230CRZ (DFN) and ISL28230CUZ (MSOP), differing primarily in the surface-mount SOIC package format. The series targets applications demanding stability without the noise penalties of chopper amplifiers.
