ISL28533FVZ

Overview

The ISL28533FVZ is a single-channel, zero-drift programmable gain instrumentation amplifier (PGIA) manufactured by Renesas Electronics Corporation. It features rail-to-rail input and output capabilities with a supply voltage range of 2.5V to 5.5V. Key electrical parameters include a gain bandwidth product of 2.3MHz, a slew rate of 0.8V/µs, and an output current capability of 45mA per channel. The device operates on a supply current of approximately 2.9mA and supports a wide industrial temperature range from -40°C to +125°C.

Feature Summary

• Zero-drift architecture ensures low offset voltage and minimal drift over temperature variations for high precision applications.
• Programmable gain functionality utilizes a unique 2-bit, 3-state logic interface to select up to nine distinct gain settings.
• Rail-to-rail input and output stages maximize dynamic range within the specified supply voltage limits.

Applications

• High precision sensor signal conditioning
• Industrial process control systems
• Medical instrumentation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific package markings against official datasheets prior to integration. Check for recent Product Change Notifications regarding labeling or manufacturing site updates to ensure compatibility with existing assembly processes.

Selection Notes

Select this component when high accuracy and stability are required in single-ended output configurations. The integrated uncommitted zero-drift amplifier allows for REF input buffering or additional precision amplification tasks. Ensure the application benefits from the selectable gain options and rail-to-rail performance within the 2.5V to 5.5V operating range.

Part Context

This part belongs to the ISL2853x series of programmable gain instrumentation amplifiers. It shares architectural similarities with the ISL2863x differential output variants but provides a single-ended output configuration. The series is designed for applications requiring high common-mode rejection and low noise over wide industrial temperature ranges.

Replacement Considerations

Direct substitutes include other members of the ISL2853x family, such as the ISL28534FVZ or ISL28535FVZ, which offer similar zero-drift characteristics and programmable gain interfaces. Verify pinout compatibility and output configuration requirements before substitution.
