ISL28430FBZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28430FBZ is a quad-channel, micropower operational amplifier from the Renesas ISL28x30 series. It features a maximum input offset voltage of 40μV and a low drift of 150nV/°C. The device operates on a single supply of +1.8V to +5.5V or dual supplies of ±0.9V to ±2.75V. Key electrical parameters include a gain-bandwidth product of 400kHz, a slew rate of 200mV/µs, and an input bias current of 250pA. Each channel draws a typical quiescent current of 20µA. The amplifier supports rail-to-rail input and output swing, with a maximum output current of 15mA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'FBZ' against official datasheets to confirm package type (typically TSSOP-14) and temperature range. Ensure compatibility with required operating conditions. Confirm RoHS compliance status as per manufacturer specifications. Cross-reference ordering information directly with Renesas Electronics to avoid discrepancies in part identification.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when system design requires low static current alongside high DC accuracy. The quad configuration reduces board space compared to single-channel alternatives. Verify that the 400kHz bandwidth meets signal frequency requirements. Consider thermal performance if multiple channels operate simultaneously at high loads.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28x30 family, which includes single (ISL28130) and dual (ISL28230) channel variants. The series is designed for applications demanding low voltage operation and high precision. The FBZ suffix indicates a specific packaging option within the broader ISL28430 product line.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes include ISL28130 for single-channel needs and ISL28230 for dual-channel requirements. Verify pinout compatibility and electrical parameter equivalence before substitution.
