ISL28430CBZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28430CBZ-T7A is a quad-channel, micro-power, low offset drift operational amplifier optimized for single-supply (+1.8V to +5.5V) and dual-supply (±0.9V to ±2.75V) operation. It features a maximum input offset voltage of 40μV, maximum offset drift of 150nV/°C, and typical quiescent current of 20μA per amplifier. The device offers rail-to-rail input and output capabilities with a bandwidth of 0.4MHz and a slew rate of 0.2V/µs. Available in an 8-pin SOIC package, it supports commercial (0°C to 70°C) and extended (-40°C to 125°C) temperature ranges.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix CBZ corresponds to the 8-pin SOIC package and tape-and-reel delivery format. Confirm the temperature grade matches the application requirements, as commercial and extended variants exist within the ISL28x30 family. Ensure compatibility with standard industry pinouts when replacing legacy components.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring multiple channels with strict power constraints. The quad topology reduces board space compared to single-channel alternatives. Verify that the 0.4MHz bandwidth meets the signal frequency requirements. Consider the 20μA quiescent current impact on total system battery life during continuous operation.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28x30 series of micro-power, low offset drift operational amplifiers from Renesas Electronics. The series includes single (ISL28130), dual (ISL28230), and quad (ISL28430) channel variants. These amplifiers are designed for high-precision analog signal processing in low-voltage environments.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes include other quad-channel op-amps with similar rail-to-rail I/O and low quiescent current specifications. Verify pinout compatibility and electrical parameter equivalence before substitution.
