Overview
The ISL28633FVZ-T7A is a single-channel, zero-drift instrumentation amplifier manufactured by Renesas Electronics. It operates on a supply voltage range of 2.5 V to 5.5 V and features a gain-bandwidth product of 2.3 MHz with a slew rate of 800 mV/µs. Key electrical parameters include an input offset voltage of 600 nV, input bias current of 400 pA, common-mode rejection ratio of 80 dB, and power supply rejection ratio of 140 dB. The device draws 3 mA of operating current and supports a common-mode voltage down to 300 mV. It functions within a temperature range of -40°C to +125°C and is housed in a TSSOP-14 surface-mount package.
Feature Summary
- Zero-drift architecture ensures high precision and stability over time and temperature variations.
- High common-mode rejection ratio and power supply rejection ratio for accurate signal conditioning.
- Low input bias current minimizes loading effects on high-impedance sensor sources.
Applications
- Precision industrial process control systems
- Medical instrumentation requiring low drift
- Strain gauge and load cell signal conditioning
Procurement Notes
Verify the specific suffix 'T7A' against official Renesas documentation to confirm tape-and-reel packaging specifications and quantity per reel. Ensure compatibility with standard SMD reflow profiles for TSSOP-14 packages. Confirm RoHS compliance status through the manufacturer's latest certification documents before finalizing procurement orders.
Selection Notes
Select this component when designing circuits that require ultra-low offset voltage drift and high CMRR in single-supply applications. It is suitable for replacing older chopper-stabilized amplifiers where improved accuracy and lower noise are critical. Consider the 3 mA quiescent current for power budget constraints in portable or battery-operated devices.
Part Context
The ISL28633 belongs to the Renesas ISL28633 series of precision instrumentation amplifiers. This series is designed for applications demanding high accuracy and stability. The device integrates zero-drift technology to eliminate offset voltage drift, making it ideal for DC-coupled signal chains in harsh environments.
Replacement Considerations
Consult official Renesas cross-reference guides for verified substitutes. Generic replacements may not match the zero-drift performance or specific pinout configurations of the TSSOP-14 package.
