ISL28535FVZ

Overview

The ISL28535FVZ is a 5V, rail-to-rail I/O, zero-drift, single-ended output programmable gain instrumentation amplifier in a TSSOP-14 package. It operates over a temperature range of -40°C to +125°C. The device features low offset, low noise, low gain error, and high CMRR. It utilizes a unique 2-bit, 3-state logic interface for up to 9 selectable gain settings. An additional uncommitted zero-drift amplifier buffers the REF input or serves as a precision amplifier.

Feature Summary

• Zero-drift architecture ensures low offset and low noise performance
• Rail-to-rail input and output capabilities on a 5V supply
• Programmable gain via 2-bit, 3-state logic interface with nine selectable settings
• Integrated auxiliary zero-drift amplifier for reference buffering

Applications

• High precision industrial sensor signal conditioning
• Medical equipment data acquisition systems
• Strain gauge and bridge sensor interfaces
• Precision measurement instruments requiring low drift

Procurement Notes

Verify the specific suffix FVZ corresponds to the TSSOP-14 package and -40°C to +125°C temperature grade. Confirm RoHS compliance status and lead times directly with Renesas Electronics Corporation or authorized distributors. Ensure the logic interface requirements match the system design before procurement.

Selection Notes

Select this component when high precision and low drift are critical over wide temperature ranges. The single-ended output variant suits applications where differential outputs are unnecessary. Consider the auxiliary amplifier utility for reference buffering. Verify power supply constraints align with the 5V operation requirement.
