ISL28130CHZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28130CHZ-T7A is a single-channel micropower operational amplifier from the Renesas ISL28x30 series. It features a gain-bandwidth product of 400 kHz and a slew rate of 200 mV/us. The device exhibits low input offset voltage of 40 uV and input bias current of 700 pA. Operating on a single supply from 1.8 V to 5.5 V, it draws 20 uA per channel with rail-to-rail input and output capabilities. It provides 125 dB CMRR and 65 nV/sqrt Hz noise density in an SC-70-5 package.

• Micropower consumption optimized for battery operation
• Low drift characteristics ensuring high precision

Instrumentation, Op Amps, Buffer Amps Applications

• Handheld devices powered by AA or single lithium-ion batteries
• Precision analog front ends in portable instrumentation
• Battery-operated medical equipment such as infusion pumps

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'T7A' against official Renesas documentation to confirm tape-and-reel quantities and marking details. Confirm the 'C' temperature grade designation matches the required operating range. Check for end-of-life status as some ISL28x30 variants are marked obsolete. Ensure the SC-70-5 footprint aligns with the design layout.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when ultra-low quiescent current is critical alongside moderate bandwidth requirements. The SC-70-5 package suits space-constrained designs. Compare against other ISL28x30 variants if dual or quad channels are needed. Verify that the 400 kHz bandwidth meets signal frequency needs. Consider thermal performance within the small package for high-density boards.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28x30 family of micropower, low-drift operational amplifiers. The family includes single (ISL28130), dual (ISL28230), and quad (ISL28430) channel versions. These amplifiers are designed for low-voltage, low-power applications requiring high accuracy. The series is characterized by its ability to operate efficiently from single or dual supplies.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for direct pin-compatible replacements within the ISL28x30 family such as ISL28130FEZ or ISL28130FHZ. Verify if newer Renesas equivalents exist for discontinued Intersil parts. Ensure any substitute maintains the SC-70-5 package and specified electrical parameters.
