ISL28278FAZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28278FAZ is a dual-channel general-purpose operational amplifier manufactured by Intersil. It features rail-to-rail output capability and operates within a supply voltage range of 2.4 V to 5.5 V. Key electrical parameters include a gain-bandwidth product of 300 kHz, an input bias current of 10 pA, and a slew rate of 0.15 V/µs. The device is housed in a 16-lead QSOP surface-mount package and supports an operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix (e.g., FAZ vs. FAZ-TZ) against the manufacturer's official datasheet to confirm packaging type and availability status. Confirm RoHS compliance and lead-free status through current documentation. Check for end-of-life notifications or discontinuance alerts from Renesas Electronics prior to finalizing procurement plans.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low power consumption and rail-to-rail output are required in a dual-op-amp configuration. Ensure the 300 kHz bandwidth meets the signal frequency requirements. Verify that the 16-QSOP package dimensions fit the PCB layout constraints and thermal management needs of the target application design.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL2827x series of precision amplifiers from Intersil, now part of Renesas Electronics. The series focuses on low-power, high-precision performance for portable and battery-operated devices. The ISL28278FAZ specifically offers dual channels in a compact surface-mount package, distinguishing it from single-channel variants or higher-speed models in the same family.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult official substitution guides for equivalents such as the ISL28276FBZ or ISL28279FAZ. Verify pin compatibility and parameter alignment before replacing. Note that some variants may be discontinued; check current production status.
