ISL28534FVZ

Overview

The ISL28534FVZ 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. The device integrates a unique 2-bit, 3-state logic interface allowing up to nine selectable gain settings. It includes an additional uncommitted zero-drift amplifier for buffering the reference input or as a precision amplifier. Key electrical parameters include a gain-bandwidth product of 2.3MHz, a slew rate of 0.8V/µs, and a supply current of 2.9mA per channel.

Feature Summary

• Zero-drift architecture ensures low offset voltage and minimal drift over temperature
• Rail-to-rail input and output operation maximizes dynamic range
• Programmable gain via 2-bit, 3-state logic interface with up to nine gain settings
• Integrated auxiliary zero-drift amplifier for reference buffering or signal conditioning

Applications

• High-precision industrial sensor signal conditioning
• Medical instrumentation requiring low drift performance
• Data acquisition systems with multiple gain requirements
• Strain gauge and bridge sensor interfaces

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm package integrity and marking consistency with official datasheets. Check for recent Product Change Notices regarding labeling or material updates. Ensure storage conditions comply with moisture sensitivity level specifications before reflow soldering.

Selection Notes

Select this component when low offset drift and high common-mode rejection are critical. The integrated auxiliary amplifier reduces external component count compared to discrete solutions. Consider the 2.3MHz bandwidth for signal frequency limitations. Evaluate power consumption against system constraints given the 2.9mA supply current.

Part Context

This part belongs to the ISL2853x series of zero-drift instrumentation amplifiers. It shares architectural similarities with the ISL28533 and ISL28535 models, differing primarily in channel configuration and output type. The series is designed for applications demanding high accuracy without frequent calibration.

Replacement Considerations

ISL28534EV2Z is an evaluation board for this device, not a direct replacement. Verify pin compatibility and electrical specifications before substituting with other PGIA models from different manufacturers.
