ISL28270IAZ-T13

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28270IAZ-T13 is a dual-channel micropower instrumentation amplifier in a 16-lead QSOP package. It operates on a single supply from 2.4V to 5.5V with rail-to-rail input and output capabilities. Key specifications include a maximum offset voltage of 150µV, a typical CMRR of 110dB, and a -3dB bandwidth of 240kHz at a gain of 100. The device features an Input Range Enhancement Circuit (IREC) for extended common-mode range and independent channel enable pins.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output operation enabled by the Input Range Enhancement Circuit (IREC)
• Micropower consumption with approximately 60µA per channel
• Independent channel enable functionality for power management
• Bipolar input devices providing low offset voltage and excellent 1/f noise performance

Instrumentation, Op Amps, Buffer Amps Applications

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

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the T13 suffix indicates tape-and-reel packaging configuration. Confirm RoHS compliance status as the datasheet notes Pb-free plus anneal products are compatible with both SnPb and Pb-free soldering operations. Check current availability as the document marks this series as not recommended for new designs.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the ISL28270 over the ISL28273 when applications require gains of 100 or higher due to internal compensation stability. Ensure the design accommodates the 16-lead QSOP thermal characteristics. Verify that the required gain setting resistors align with the high impedance feedback terminals to maintain specified CMRR performance.
