ISL28633FVZ-T13

Overview

The ISL28633FVZ-T13 is a single-channel zero-drift instrumentation amplifier manufactured by Renesas Electronics. It operates within 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/us. Key electrical specifications 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 of 300 mV. It is housed in a TSSOP-14 surface-mount package and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Zero-drift architecture minimizes offset voltage drift over temperature variations
• High precision signal conditioning capabilities for low-level sensor inputs
• Integrated design reduces component count compared to discrete solutions

Applications

• Precision industrial process control systems
• Medical diagnostic equipment requiring high accuracy
• Strain gauge and load cell measurement interfaces

Procurement Notes

Verify the specific suffix T13 corresponds to the required tape and reel packaging configuration before ordering. Confirm that the TSSOP-14 footprint matches the target PCB layout dimensions. Ensure the operating environment remains within the specified -40°C to +125°C thermal limits to maintain guaranteed performance parameters. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when ultra-low offset voltage and minimal drift are critical requirements for the application. The zero-drift technology eliminates the need for external chopper stabilization circuits. Consider the 3 mA supply current consumption against available power budgets. The TSSOP-14 package offers a compact solution for space-constrained designs requiring high-density mounting.

Part Context

This instrument belongs to the ISL28633 series of zero-drift amplifiers designed for high-precision applications. The series provides enhanced stability and accuracy compared to standard chopper-stabilized amplifiers. It serves as a direct replacement for legacy Intersil instrumentation amplifiers in existing designs. The family focuses on delivering rail-to-rail output capability with minimal noise interference.

Replacement Considerations

Check datasheet compatibility for pinout and electrical characteristics when substituting older Intersil variants. Verify that the TSSOP-14 package dimensions align with existing board footprints. Ensure the new unit meets the same thermal and voltage specifications required by the original design.
