ISL28635FVZ

Overview

The ISL28635FVZ is a single-channel, zero-drift, rail-to-rail input/output programmable gain instrumentation amplifier (PGIA) manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.5 V to 5.5 V and features a low offset voltage of 5 µV, input bias current of 400 pA, and common-mode rejection ratio of 100 dB. The device delivers a slew rate of 800 mV/µs and a gain-bandwidth product of 2.3 MHz with a power supply rejection ratio of 140 dB. It consumes 3.6 mA of operating current and is housed in a TSSOP-14 package, supporting an industrial temperature range from -40°C to +125°C.

Feature Summary

• Zero-drift architecture ensures high precision and stability over wide industrial temperature ranges.
• Programmable gain functionality enabled by a unique 2-bit, 3-state logic interface for flexible signal conditioning.
• Rail-to-rail input and output capabilities maximize dynamic range in low-voltage applications.

Applications

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

Procurement Notes

Verify the specific suffix 'T13' against the requested model 'ISL28635FVZ', as it indicates tape-and-reel packaging which may differ from tube distribution. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Ensure the supplier provides official datasheets matching the exact part number to validate electrical parameters and pinout configurations.

Selection Notes

Select this component when high accuracy and low drift are critical for single-ended or differential signal amplification. The integrated programmable gain reduces external component count compared to discrete solutions. Consider the TSSOP-14 package constraints and thermal performance for PCB layout. Verify that the 2.5 V to 5.5 V supply range aligns with system power rails.

Part Context

This device belongs to the ISL2863x series of zero-drift instrumentation amplifiers. It shares architectural similarities with the ISL28535 but differs in output configuration, offering differential output characteristics suitable for noise-immune applications. The series is designed for demanding environments requiring stable performance without frequent calibration.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other members of the ISL2863x family only if functional differences such as output type are acceptable.
