ISL28430CVZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28430CVZ is a quad-channel micro-power operational amplifier from the Renesas ISL28x30 series, optimized for low-voltage and low-power applications. It features a maximum input offset voltage of 40μV and a typical quiescent current of 20μA per channel. The device operates on a single supply voltage ranging from 1.8V to 5.5V or dual supplies of ±0.9V to ±2.75V. It offers rail-to-rail input and output capabilities with a gain-bandwidth product of 400kHz and a slew rate of 200mV/μs. The component is housed in a 14-lead TSSOP package and supports commercial temperature operation from 0°C to +70°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'CVZ' against official datasheets to confirm the package type (TSSOP) and temperature grade (Commercial). Ensure compatibility with existing PCB footprints for 14-lead TSSOP components. Confirm that the quad-channel configuration meets system requirements without exceeding available board space or thermal limits.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing circuits that demand both high accuracy and minimal power draw from limited voltage sources. The rail-to-rail I/O allows signal swings close to supply rails, maximizing headroom in low-voltage systems. Consider the 400kHz bandwidth for applications requiring moderate speed without excessive power dissipation.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28x30 family of micro-power op-amps, which includes single (ISL28130) and dual (ISL28230) channel variants. The family shares identical electrical characteristics but differs in channel count and packaging options. This series is designed to replace older precision amplifiers while offering significantly lower static current consumption suitable for battery-operated environments.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible replacements within the same family include ISL28130 and ISL28230 if fewer channels are acceptable. Verify that any substitute maintains the 40μV max Vos and 20μA IQ specifications to ensure circuit performance remains unchanged.
