ISL28168FHZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28168FHZ-T7 is a single-channel, micro-power operational amplifier manufactured by Intersil (Renesas). It features rail-to-rail input and output capabilities within a compact SOT-23-6 surface-mount package. Key electrical specifications include a gain-bandwidth product of 200 kHz, a supply current of 34 µA per channel, and an output drive capability of 30 mA. The device operates with supply voltages ranging from 1.8 V to 5.5 V and supports an extended industrial temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Micro-power consumption with 34 µA supply current per channel
• Rail-to-rail input and output operation for maximum dynamic range
• Compact SOT-23-6 surface-mount packaging for space-constrained designs

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered portable instrumentation
• Low-voltage signal conditioning circuits
• Sensor interface applications requiring high efficiency

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer marking on the component body to confirm it reads 'ISL' or 'Renesas' corresponding to the ISL28168 series. Ensure the package code matches the SOT-23-6 footprint dimensions specified in the official datasheet. Check for moisture sensitivity labels if the component has been stored for extended periods, as indicated in related family documentation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low quiescent current is critical alongside rail-to-rail performance. It is suitable for single-supply systems operating between 1.8 V and 5.5 V. Compare against higher-speed variants like the ISL28191 if bandwidth requirements exceed 200 kHz. Consider the 30 mA output drive limit for load matching.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL281xx family of micro-power operational amplifiers from Intersil, now part of Renesas Electronics. The family includes dual and quad variants such as the ISL28158 and ISL28168. These devices are designed for general-purpose analog applications where power efficiency and small form factors are prioritized over high-speed slew rates.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible substitutes within the same family include the ISL28158FHZ-T7 (dual channel) or ISL28168FBZ-T7 (different package). Cross-family replacements require verification of gain-bandwidth and supply voltage compatibility.
