ISL28233FBZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28233FBZ-T7A is a dual precision operational amplifier manufactured by Renesas Electronics Corporation. It features micro power consumption with rail-to-rail input and output (RRIO) capabilities, making it suitable for low-voltage applications. The device operates within a supply voltage range of 1.8 V to 5.5 V. Key electrical specifications include a gain-bandwidth product of 340 kHz, a slew rate of 200 mV/µs, an input offset voltage of 2 µV, and an input bias current of 37 pA. It provides a common-mode rejection ratio of 106 dB and consumes 22 µA of operating supply current per channel.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the complete part number including the suffix 'T7A' to ensure correct tape-and-reel packaging configuration. Confirm that the 'FBZ' designation matches the required SOIC-8 package variant. Cross-reference the manufacturer date code against project lifecycle requirements to avoid obsolescence risks. Ensure compatibility with RoHS directives if applicable to your region. Validate that the 1.8V minimum supply voltage aligns with your system's power rails.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both low quiescent current and high DC accuracy are critical. The 340 kHz bandwidth supports moderate-speed signals while maintaining ultra-low noise characteristics. Compare against higher-speed amplifiers if signal frequency exceeds typical audio or slow sensor ranges. Consider the 2 µV offset voltage for applications requiring minimal calibration. Ensure the 8-SOIC package fits the PCB layout constraints compared to smaller alternatives like SC-70.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28233 family of dual precision amplifiers from Renesas, formerly Intersil. It is distinct from single-channel variants like the ISL28133 or higher-performance models in the series. The FBZ-T7A suffix indicates a specific surface-mount package and reel quantity configuration. It serves as a bridge between general-purpose op-amps and specialized chopper-stabilized amplifiers, offering a balance of speed, power, and precision.
