ISL28271FAZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28271FAZ is a dual micropower instrumentation amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply voltage ranging from 2.4 V to 5.5 V, or dual supplies of ±1.2 V to ±2.75 V. The device offers a maximum input offset voltage of 35 µV and a gain bandwidth product of 0.18 MHz. With a slew rate of 0.5 V/µs, it is designed for low-power applications requiring high precision in signal conditioning.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix (T7) for tape-and-reel packaging if required. Confirm current availability status as Intersil products are managed by Renesas Electronics. Check for Product Change Notices (PCN) regarding manufacturing site changes or component updates. Ensure compatibility with existing PCB footprints for 16-QSOP packages during procurement planning.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when dual-channel precision amplification is needed with minimal power consumption. The rail-to-rail feature allows for maximum dynamic range in low-voltage single-supply systems. Consider the 0.18 MHz bandwidth for applications requiring moderate speed without excessive power draw. Verify that the 35 µV max offset meets system accuracy requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

Intersil was acquired by Renesas Electronics, which now manages the legacy product line. The ISL28271 series belongs to the micropower instrumentation amplifier family. This specific part number represents the non-suffix version in a 16-QSOP package, distinct from the T7 reel variant. It serves as a bridge between general-purpose op-amps and higher-performance dedicated instrumentation amplifiers.
