ISL28230FRZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28230FRZ is a dual-channel micro-power operational amplifier from the Renesas ISL28x30 series. It features rail-to-rail input and output capabilities, optimized for single-supply operation from 1.8V to 5.5V or dual supplies of ±0.9V to ±2.75V. Key electrical parameters include a gain-bandwidth product of 400 kHz, a slew rate of 200 mV/µs, an input offset voltage of 40 µV, and an input bias current of 250 pA. The device operates with a quiescent current of 20 µA per channel and provides an output current of 15 mA. It is housed in an SOIC-8 surface-mount package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix FRZ indicates the SOIC-8 package variant when sourcing. Confirm the component status as end-of-life or obsolete prior to procurement planning. Ensure compatibility with RoHS standards if required by the target application. Cross-reference the manufacturer datasheet for exact thermal and mechanical dimensions to validate PCB footprint requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications demanding high precision with minimal power consumption. The dual-channel configuration suits designs requiring two independent amplifiers in a compact form factor. Consider the SOIC-8 package for standard surface-mount assembly processes. Evaluate the 400 kHz bandwidth against the maximum signal frequency requirements of the specific circuit topology.

Instrumentation, Op Amps, Buffer Amps Part Context

The ISL28230FRZ belongs to the ISL28x30 family of zero-drift amplifiers, which includes single (ISL28130) and quad (ISL28430) variants. This family shares core architectural features such as chopper stabilization for low offset voltage and micro-power operation. The FRZ suffix specifically denotes the SOIC-8 package option within this series, distinguishing it from MSOP or DFN alternatives.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible substitutes within the same series include ISL28230FUZ (MSOP-8) and ISL28230CRZ (DFN-8). Verify package dimensions and thermal characteristics when substituting between different footprints. Ensure that the replacement part maintains the same electrical specifications for offset voltage, bandwidth, and supply voltage range.
