ISL28635FVZ-T7A

Overview

The ISL28635FVZ-T7A is a single-channel, zero-drift programmable gain instrumentation amplifier from the Renesas ISL28635 series. It operates on a single supply voltage ranging from 2.5 V to 5.5 V 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. Key electrical specifications include an input offset voltage of 5 µV, a common-mode rejection ratio of 100 dB, and a power supply rejection ratio of 140 dB. It is housed in a TSSOP-14 package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Zero-drift architecture ensures low offset voltage and minimal drift over temperature variations.
• Programmable gain functionality allows selection of up to nine gain settings via a 2-bit, 3-state logic interface.
• Rail-to-rail input and output stages maximize dynamic range within the supply voltage limits.

Applications

• High precision industrial sensor signal conditioning
• Medical instrumentation data acquisition systems
• Strain gauge and bridge sensor interfaces

Procurement Notes

Verify the specific suffix 'T7A' against official Renesas documentation to confirm tape and reel quantity and packaging details, as datasheets often reference standard suffixes like 'T13'. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm availability status directly with authorized distributors or the manufacturer, as lead times and stock levels fluctuate.

Selection Notes

Select this component when high accuracy and stability are required in single-supply environments. The zero-drift technology eliminates the need for external chopper stabilization circuits. Consider the available gain settings and the logic interface compatibility with your microcontroller or control system. Verify that the TSSOP-14 package fits your PCB layout constraints and thermal management requirements.
