ISL28230FBZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28230FBZ-T7A is a dual-channel micro-power, zero-drift operational amplifier manufactured by Renesas Electronics Corporation. It features rail-to-rail input and output capabilities, making it suitable for low-voltage single-supply applications. The device operates within a supply voltage range of 1.8 V to 5.5 V or ±0.9 V to ±2.75 V in dual-supply configurations. Key electrical specifications include a maximum input offset voltage of 40 µV, an input bias current of 250 pA, and a typical quiescent current of 20 µA per amplifier. The gain-bandwidth product is 400 kHz with a slew rate of 0.2 V/µs. It is housed in an 8-SOIC surface-mount package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'FBZ' against official Renesas documentation to confirm the SOIC-8 package variant, as datasheets may list multiple package options for the ISL28230 family. Confirm the operating temperature grade (industrial vs. commercial) matches the application requirements. Check for obsolescence notices or PCNs regarding packaging changes before finalizing procurement plans.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing circuits that demand high DC precision without the complexity of chopper stabilization artifacts. It is appropriate for applications where low supply current is critical but moderate bandwidth is sufficient. Ensure the PCB layout accommodates the sensitivity of the high-impedance inputs to minimize noise pickup.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28x30 series of micro-power, zero-drift amplifiers. The series includes single-channel (ISL28130), dual-channel (ISL28230), and quad-channel (ISL28430) variants. These amplifiers are optimized for low-voltage operation and offer superior performance compared to standard CMOS op-amps in terms of offset voltage and drift.
