ISL28138FHZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28138FHZ-T7A is a single-channel general-purpose operational amplifier manufactured by Intersil. It features a 4.5 MHz gain bandwidth product and a slew rate supporting rail-to-rail output swing. The device operates on supply voltages ranging from 2.4V to 36V with a typical supply current of 900µA per amplifier. Key electrical specifications include a maximum input offset voltage of 300µV and a typical input bias current of 1pA. It is housed in a compact SOT-23-6 package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail output capability for extended dynamic range
• Low input bias current for high impedance applications
• Single-supply operation down to 2.4V

Instrumentation, Op Amps, Buffer Amps Applications

• Signal conditioning circuits
• Sensor interface amplification
• Active filtering

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'T7A' against official Renesas/Intersil documentation to confirm tape-and-reel packaging and temperature grade. Ensure compatibility with existing PCB footprints for the SOT-23-6 package. Cross-reference manufacturer part numbers as Intersil products are now managed under Renesas Electronics.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel op amp with rail-to-rail output is required in a small footprint. It is suitable for battery-powered systems due to low supply current. Compare against other ISL281xx series variants if higher precision or different bandwidths are needed.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL281xx family of precision operational amplifiers. The family offers various configurations including single, dual, and quad channels with differing bandwidth and precision levels. The FHZ suffix indicates the SOT-23-6 package variant.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for direct pin-compatible substitutes within the ISL281xx series such as ISL28138FHZ-T7. Verify that alternative parts meet the same 4.5MHz bandwidth and 300µV offset voltage requirements.
