ISL28430CVZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28430CVZ-T7A is a quad-channel micro-power 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 single supplies from +1.8V to +5.5V or dual supplies of ±0.9V to ±2.75V, with a typical quiescent current of 20µA per channel. Key electrical parameters include a gain-bandwidth product of 400kHz, a slew rate of 200mV/µs, an input bias current of 250pA, and a common-mode rejection ratio of 125dB. It supports rail-to-rail input and output operation.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the suffix 'T7A' indicates tape and reel packaging configuration. Confirm the 'C' designation corresponds to the commercial temperature range (0°C to +70°C) as specified in the datasheet. Ensure the quad-channel variant matches system requirements compared to single or dual-channel alternatives.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when system design demands low static power alongside high DC accuracy. The quad-channel architecture reduces board space compared to discrete solutions. Verify that the 400kHz bandwidth meets signal processing needs and that the 250pA bias current is compatible with source impedance limitations.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28x30 family of micro-power, low-offset amplifiers. It serves as the four-channel version within the series, complementing the ISL28130 (single) and ISL28230 (dual). The series is engineered for applications where power efficiency and signal integrity are critical constraints.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes include ISL28130 and ISL28230 for reduced channel counts. Verify pinout compatibility if replacing with other quad-channel op-amps. Check thermal and electrical specifications against original design margins.
