ISL28156FHZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28156FHZ-T7 is a micropower precision operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply voltage ranging from 2.4V to 5.5V or dual supplies of ±1.2V to ±2.5V, consuming a typical supply current of 39µA when enabled. The device includes an Input Range Enhancement Circuit (IREC) allowing inputs to swing up to 0.5V above the positive rail. Key electrical specifications include a gain bandwidth product of 250kHz, a maximum input offset voltage of 400µV in the SOT-23 package, and a maximum input bias current of 5nA.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Features an enable pin that reduces supply current to typically 10µA in the disabled state, facilitating multiplexer configurations with tied outputs.
• Incorporates an Input Range Enhancement Circuit (IREC) to maintain common-mode rejection ratio performance for input voltages exceeding the positive supply rail.
• Provides rail-to-rail output capability with bipolar inputs extending slightly beyond the positive supply and near the negative rail.

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered systems
• Solar-powered systems
• 4mA to 20mA current loops
• Handheld consumer products
• Medical devices

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix T7 indicates tape-and-reel packaging configuration. Confirm the component is sourced from authorized distributors to ensure authenticity. Check for RoHS compliance status as indicated in the datasheet documentation. Ensure the selected package variant matches the required PCB footprint dimensions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low quiescent current alongside precision signal conditioning. The IREC feature is critical for circuits where input signals may exceed the positive supply voltage. Consider the thermal resistance characteristics of the 6-lead SOT-23 package for power dissipation calculations under heavy load conditions.
