ISL28230CUZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28230CUZ 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. Key electrical specifications include a maximum input offset voltage of 40 µV, a typical quiescent current of 20 µA per channel, and an input bias current of 250 pA. It utilizes an 8-lead MSOP package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Zero-drift architecture ensures low input offset voltage and minimal drift over temperature variations.
• Rail-to-rail input and output stages maximize dynamic range in low-voltage systems.
• Micro-power consumption with 20 µA supply current per amplifier supports battery-operated designs.

Instrumentation, Op Amps, Buffer Amps Applications

• Handheld devices powered by 2AA batteries or single lithium-ion cells
• Precision sensor signal conditioning
• Medical instrumentation such as infusion pumps

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'CUZ' against the official datasheet to confirm the commercial temperature grade (0°C to 70°C) and MSOP-8 packaging. Confirm RoHS compliance status and check for any End-of-Life notices or Product Change Notifications from Renesas prior to finalizing procurement plans.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low power consumption and high precision are required in space-constrained designs. The dual-channel configuration reduces board space compared to single-channel alternatives. Ensure the application voltage stays within the 1.8 V to 5.5 V range to maintain specified performance metrics.

Instrumentation, Op Amps, Buffer Amps Part Context

The ISL28230CUZ belongs to the ISL28x30 family of zero-drift amplifiers, which includes single-channel (ISL28130) and quad-channel (ISL28430) variants. This family is designed for applications requiring high accuracy and low power, such as portable medical equipment and industrial sensors. The CUZ suffix denotes the commercial temperature range and MSOP package.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations
