ISL28230FBZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28230FBZ 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 applications. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V or dual supplies of ±0.9 V to ±2.75 V. Key electrical parameters include a maximum input offset voltage of 40 µV, a typical quiescent current of 20 µA per amplifier, and a gain-bandwidth product of 400 kHz. The component is housed in an 8-lead TSSOP package.

• Medical instrumentation

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'FBZ' against official Renesas documentation to confirm the 8-lead TSSOP package configuration. Ensure compatibility with the required operating temperature range and pinout assignments before integration. Cross-reference datasheet revisions to confirm current manufacturing status and any recent design changes.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low power consumption and high precision are critical in space-constrained designs. The dual-channel configuration reduces board space compared to single-channel alternatives. Verify that the 400 kHz bandwidth meets the signal frequency requirements and that the TSSOP package fits the PCB layout constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

The ISL28230FBZ belongs to the ISL28x30 family of zero-drift amplifiers, which includes single (ISL28130) and quad (ISL28430) variants. This family is designed for applications requiring high accuracy and low power. The FBZ suffix specifically denotes the dual-channel version in an 8-lead TSSOP package, distinguishing it from other package options like SOIC or DFN.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Compatible substitutes within the same family include ISL28130 (single channel) and ISL28430 (quad channel), provided the channel count difference is acceptable. Other packages such as ISL28230CRZ (DFN) or ISL28230FUZ (MSOP) offer similar electrical performance but require different footprint considerations.
