ISL28535FVZ-T7A

Overview

The ISL28535FVZ-T7A is a single-ended output, zero-drift, programmable gain instrumentation amplifier (PGIA) manufactured by Renesas Electronics. It operates on a single 5V supply and features rail-to-rail input and output capabilities. The device utilizes a unique 2-bit, 3-state logic interface to select up to nine distinct gain settings. It incorporates an additional uncommitted zero-drift amplifier within the package, which can be utilized to buffer the reference input or function as a precision amplifier. The component is housed in a TSSOP-14 package and supports an industrial operating temperature range from -40°C to +125°C.

Feature Summary

• Zero-drift architecture ensures low offset voltage and low noise for high precision applications
• Rail-to-rail input and output capability allows operation across the full supply voltage range
• Programmable gain via 2-bit, 3-state logic interface provides up to nine selectable gain settings
• Integrated uncommitted zero-drift amplifier available for reference buffering or auxiliary amplification

Applications

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

Procurement Notes

Verify that the specific suffix 'T7A' corresponds to the tape and reel packaging configuration as defined in the official datasheet. Confirm the manufacturer designation is Renesas Electronics, noting the historical Intersil branding often associated with this product line. Ensure the order quantity matches the specified reel size requirements for automated assembly processes.

Selection Notes

Select this component when high accuracy and stability are required over wide temperature variations without frequent calibration. The integrated uncommitted amplifier offers design flexibility for reference management. Consider the TSSOP-14 package constraints for PCB layout. Verify that the logic interface pins align with the system's microcontroller or control logic availability.

Part Context

This part belongs to the ISL2853x series of zero-drift instrumentation amplifiers. It shares architectural similarities with differential output variants like the ISL28635 but provides a single-ended output configuration. The series is designed for applications demanding high common-mode rejection ratio (CMRR) and minimal gain error in harsh industrial environments.

Replacement Considerations

Consult official documentation for direct pin-compatible substitutes within the ISL2853x family. Verify functional equivalence regarding gain settings and amplifier configurations before substitution.
