ISL28233FUZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28233FUZ is a dual micropower, chopper stabilized operational amplifier from Renesas. It features rail-to-rail inputs and outputs (RRIO) and operates on single supplies from +1.65V to +6.0V or dual supplies from ±0.825V to ±3.0V. Key electrical parameters include a maximum input offset voltage of 6µV, typical quiescent current of 18µA per amplifier, and a gain-bandwidth product of 400kHz. The device offers low noise performance with 1.0µVP-P typical noise in the 0.01Hz to 10Hz range.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Chopper stabilization technology ensures ultra-low offset voltage and drift for high precision applications.
• Rail-to-rail input and output capability maximizes dynamic range in low-voltage systems.
• Micropower consumption design enables extended battery life in portable devices.

Instrumentation, Op Amps, Buffer Amps Applications

• Bidirectional current sensing
• Precision temperature measurement
• Electronic weighing scales
• Strain gauge sensor interfaces

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'FUZ' against official Renesas documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint requirements for the designated package style. Confirm availability status as product lifecycles may change without prior notice.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low offset voltage and micro-power operation are critical constraints. The RRIO feature makes it suitable for single-supply designs where signal swing must approach supply rails. Verify that the 400kHz bandwidth meets the frequency response requirements of the target application circuit.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28233 series of zero-drift amplifiers. It is designed for general-purpose precision applications requiring high accuracy at very low power levels. The series is optimized for handheld devices powered by AA or Li-ion batteries.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for direct pin-compatible alternatives within the ISL28233 family, such as single-channel variants if only one amplifier is needed. Verify that any substitute maintains the same chopper-stabilized architecture and RRIO characteristics to ensure circuit compatibility.
