ISL28108FBZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28108FBZ is a single-channel, low-power operational amplifier manufactured by Renesas Electronics Corporation. It features rail-to-rail output capability and operates on a single supply voltage ranging from 3 V to 40 V, or dual supplies of ±1.5 V to ±20 V. Key electrical parameters include a gain-bandwidth product of 1.2 MHz, a slew rate of 450 mV/µs, and an input offset voltage of 150 µV. The device draws a typical operating supply current of 185 µA per channel and provides an output current of 19 mA. It offers a common-mode rejection ratio of 123 dB and an input voltage noise density of 15.8 nV/√Hz. The component is housed in an SOIC-8 surface-mount package and supports an extended operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'FBZ' against the manufacturer's official datasheet to confirm the exact packaging configuration and RoHS compliance status. Ensure the ordering part number matches the required tape-and-reel or tube quantity specifications. Cross-reference the manufacturing date code and lot traceability requirements with the supplier's certification documents prior to final procurement to ensure compatibility with assembly processes.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single op-amp with rail-to-rail output is required under a wide single-supply voltage range. It is appropriate for applications demanding low quiescent current alongside moderate bandwidth and high precision. Consider the SOIC-8 package constraints for thermal management and PCB layout. Verify that the input common-mode voltage range and output swing requirements align with the system's signal levels at the intended operating temperatures.

Instrumentation, Op Amps, Buffer Amps Part Context

The ISL28108FBZ belongs to the ISL2810x series of low-power operational amplifiers from Renesas (formerly Intersil). This family is designed to provide high performance in low-power applications. The FBZ suffix typically denotes a specific package variant and environmental compliance status within the broader ISL28108 product line, distinguishing it from other pin-compatible or functionally similar variants in the series.
