ISL28470FAZ-T7

Overview

The ISL28470FAZ-T7 is a quad-channel micropower instrumentation amplifier optimized for single-supply operation within the +2.4V to +5.5V range. It features rail-to-rail input and output capabilities, supported by an Input Range Enhancement Circuit (IREC) that maintains high common-mode rejection ratio performance near supply rails. The device utilizes bipolar input devices for low offset voltage and excellent low-frequency noise characteristics. Internally compensated for a minimum gain of 100, it offers a -3dB bandwidth of 240kHz at this gain setting.

Feature Summary

• Quad-channel architecture with independent enable pins for power management
• Rail-to-rail input and output operation enabled by Input Range Enhancement Circuit
• Bipolar input stage providing low offset voltage and minimal 1/f noise
• High impedance feedback terminals allowing precise gain setting without CMRR degradation

Applications

• Battery or solar-powered systems
• Strain gauge signal conditioning
• Medical devices
• Industrial instrumentations

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance and Pb-free status as specified in ordering information. Check datasheet revision FN6260 Rev 6.00 for current specifications. Ensure proper handling for ESD-sensitive components during storage and assembly.

Selection Notes

Select this component when four independent instrumentation amplifiers are required in a single package. Suitable for applications needing rail-to-rail input capability with high common-mode rejection. Verify gain requirements meet the minimum internal compensation threshold of 100. Consider thermal dissipation in the 28-lead QSOP package for continuous operation.

Part Context

Part of the ISL28270, ISL28273, and ISL28470 family of micropower instrumentation amplifiers. Shares core architectural features including IREC technology and bipolar input stages. Differs from dual-channel variants by offering four isolated channels in a 28-lead QSOP package. Designed for precision signal conditioning in space-constrained single-supply environments.
