ISL28535FVZ-T13

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28535FVZ-T13 is a single-channel, 5V zero-drift programmable gain instrumentation amplifier (PGIA) manufactured by Renesas Electronics. It features rail-to-rail input and output capabilities within a TSSOP-14 package. Key electrical parameters include an input offset voltage of 5 µV, a common-mode rejection ratio of 100 dB, and an input bias current of 400 pA. The device operates with a supply voltage range of 2.5 V to 5.5 V and consumes 3.6 mA of operating current. It offers a gain-bandwidth product of 2.3 MHz and a slew rate of 800 mV/µs. The power supply rejection ratio is 140 dB, and it functions reliably across a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'T13' indicates tape and reel packaging when ordering. Confirm the manufacturer designation as Renesas or Intersil on the datasheet. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the Mouser part number 968-ISL28635FVZ-T13 if available, noting potential model discrepancies in distributor listings. Validate the humidity sensitivity level before storage.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high accuracy without external trimming. The integrated zero-drift technology eliminates chopper stabilization noise spikes. Consider the TSSOP-14 package size for space-constrained PCB layouts. Verify that the 5V supply constraint aligns with the system power budget. The single-ended output variant is distinct from differential output models in the same series.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL2853x family of 5V programmable gain instrumentation amplifiers. It shares architectural similarities with the ISL2863x series but provides a single-ended output instead of differential. The device integrates an additional uncommitted zero-drift amplifier useful for buffering the reference input. It is designed for wide industrial temperature ranges and high common-mode rejection scenarios.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for ISL28535FVZ variants with different packaging options. Review ISL28635FVZ for differential output requirements. Verify pin compatibility with other members of the ISL2853x series before substitution.
