ISL28258FUZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28258FUZ is a single-channel precision operational amplifier manufactured by Renesas Electronics. It features a gain-bandwidth product of 200 kHz and a slew rate of 100 mV/us. The input offset voltage is specified at 300 uV, with an input bias current of 1.5 nA. Operating from a supply voltage range of 2.75 V to 5.5 V, it draws 530 uA of quiescent current per channel. The device supports rail-to-rail output and offers a common-mode rejection ratio of 120 dB. Input voltage noise density is 64 nV/sqrt Hz. It operates within a temperature range of -40 C to +125 C and is housed in an SOIC-8 package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'FUZ' against the official Renesas datasheet to confirm the package type and tape/reel or tube packaging configuration. Ensure the component meets RoHS compliance requirements for the target market. Confirm availability status as distribution channels may list limited stock or end-of-life notices for this specific part number variant.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the ISL28258FUZ when a single-channel amplifier with rail-to-rail output is required. Compare the 200 kHz bandwidth and 300 uV offset voltage against system requirements. Consider the 2.75 V minimum supply voltage for low-voltage designs. Evaluate the 120 dB CMRR for noise-sensitive environments. Verify thermal performance within the -40 C to +125 C operating range.

Instrumentation, Op Amps, Buffer Amps Part Context

The ISL28258 series belongs to Renesas' portfolio of micro-power precision amplifiers. This family emphasizes low energy usage while maintaining high DC accuracy. The single-channel configuration distinguishes it from dual or quad variants like the ISL28259. It targets applications where space and power constraints are critical alongside signal integrity.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for pin-compatible alternatives within the ISL282xx series. Verify if the ISL28258FBZ offers identical electrical characteristics with different packaging. Consult Renesas documentation for any newer generations replacing this component.
