ISL28635FVZ-T13

Overview

The ISL28635FVZ-T13 is a single-channel, zero-drift, rail-to-rail input/output programmable gain instrumentation amplifier (PGIA) manufactured by Renesas Electronics Corporation. It operates on a single supply voltage ranging from 2.5 V to 5.5 V and features a unique 2-bit, 3-state logic interface for selectable gain settings. The device offers low offset voltage of 5 µV, low noise, high common-mode rejection ratio (CMRR) of 100 dB, and power supply rejection ratio (PSRR) of 140 dB. With a slew rate of 800 mV/µs and a gain-bandwidth product of 2.3 MHz, it supports precision signal conditioning in industrial environments across an operating temperature range of -40°C to +125°C.

Feature Summary

• Zero-drift architecture ensures minimal offset voltage drift over temperature and time
• Rail-to-rail input and output capabilities maximize dynamic range
• Programmable gain via 2-bit, 3-state logic interface allows flexible configuration
• High common-mode rejection ratio maintains accuracy in noisy environments

Applications

• High-precision industrial sensor signal conditioning
• Medical instrumentation requiring low drift performance
• Data acquisition systems with programmable gain requirements
• Strain gauge and thermocouple amplification

Procurement Notes

Verify the complete part number including the suffix T13, which indicates tape and reel packaging, against official Renesas documentation to ensure correct ordering specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and current availability status.

Selection Notes

Select this component when designing circuits requiring ultra-low offset drift and high CMRR in a single-supply environment. The programmable gain feature reduces external component count compared to fixed-gain alternatives. Ensure the application voltage stays within the 2.5 V to 5.5 V range and that the logic interface pins are properly configured for the desired gain setting.

Part Context

This device belongs to the ISL2863x series of zero-drift instrumentation amplifiers. It shares architectural similarities with other members like the ISL28633 and ISL28634 but differs in channel count and specific pinout configurations. The series is designed for applications demanding high accuracy without the complexity of chopper stabilization external components.

Replacement Considerations

Direct replacements include other models within the ISL2863x family such as ISL28633 or ISL28634, provided pin compatibility and gain configuration requirements match. Verify functional equivalence regarding offset voltage, bandwidth, and package dimensions before substitution.
