ISL28274FAZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28274FAZ is a micropower, single-supply instrumentation amplifier and precision operational amplifier combination in a single package. It integrates a micropower instrumentation amplifier (Amp A) with a low power precision amplifier (Amp B). The device is optimized for operation at 2.4V to 5V single supplies. Inputs and outputs operate rail-to-rail. Key electrical specifications include a maximum supply current of 120µA, a maximum input offset voltage of 400µV for the instrumentation amplifier and 225µV for the operational amplifier, and a maximum input bias current of 30pA. It provides 100dB common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR).

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through authorized Renesas or Intersil distributors due to potential counterfeit risks. Confirm RoHS compliance status as the datasheet indicates Pb-free plus anneal availability. Check for recent Product Change Notifications (PCN) regarding manufacturing site changes or packaging updates. Ensure storage conditions account for moisture sensitivity levels specified in the official documentation before assembly.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when space constraints require integrating both instrumentation and general-purpose amplification functions. It is suitable for applications requiring high common-mode rejection and low power consumption. Verify that the required supply voltage falls within the 2.4V to 5.0V range. Consider the input offset voltage specifications if high DC accuracy is critical for the signal chain design.

Instrumentation, Op Amps, Buffer Amps Part Context

The ISL28274 belongs to the ISL2827x family of micropower single-supply rail-to-rail input/output instrumentation amplifiers. This series includes dual-channel variants like the ISL28270. The family is designed for battery-powered and portable applications where low current draw and high precision are necessary. The FAZ suffix typically denotes a specific package type and lead finish compliant with environmental standards.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes may include other parts from the ISL2827x family depending on channel count requirements. Verify pin compatibility and electrical parameter overlaps before substitution. Consult the manufacturer's cross-reference guide for updated alternatives if discontinuation notices apply.
