ISL28230FUZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28230FUZ is a dual-channel micro-power operational amplifier from the Renesas ISL28x30 series, housed in an MSOP-8 package. It features rail-to-rail input and output capabilities with a gain-bandwidth product of 400 kHz and a slew rate of 200 mV/us. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V or dual supplies of ±0.9 V to ±2.75 V. Key electrical specifications include a maximum input offset voltage of 40 µV, input bias current of 250 pA, and quiescent current of 20 µA per channel. It offers a common-mode rejection ratio of 105 dB and input voltage noise density of 65 nV/sqrt Hz, functioning within a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence risks associated with older Intersil branding. Confirm package integrity upon receipt as moisture sensitivity requires proper handling. Cross-reference datasheet revisions to ensure compatibility with specific design requirements before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low power consumption and high precision are required in space-constrained designs. The dual-channel configuration reduces board space compared to single-channel alternatives. Ensure the application does not require shutdown functionality, as this variant lacks it. Verify that the 400 kHz bandwidth meets signal processing needs.

Instrumentation, Op Amps, Buffer Amps Part Context

Part of the ISL28x30 family which includes single (ISL28130) and quad (ISL28430) channel variants. Manufactured by Renesas Electronics following the acquisition of Intersil. Designed for general-purpose precision amplification in portable and industrial systems requiring low noise and stability.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consider ISL28230CRZ for leaded SOIC-8 packaging options. Evaluate ISL28230FUZ-T7A for tape-and-reel delivery formats if automated assembly is required. Check for newer equivalents in the RRA786x0 series if updated manufacturing support is needed.
