Texas Instruments AMC-AMP-50A-EVM Amplifier Evaluation Module (EVM)

Texas Instruments AMC-AMP-50A-EVM Amplifier Evaluation Module (EVM) is an isolated current-sensing evaluation module designed for ±50A shunt-based current sensing. This evaluation module allows users to sense up to ±50A peak current through an external shunt resistor while measuring the isolated output through the isolation barrier of the AMC3302. The AMC3302 is a precision, isolated amplifier optimized for shunt-based current measurements and is paired with the Isabellenhütte BVN-M-R001 shunt resistor. The Texas Instruments AMC-AMP-50A-EVM features via stitching to facilitate heat dissipation at large currents and can perform within ±1% (typical) accuracy.

Features

  • ±50A isolated current sensing
  • Heat dissipation design up to 180°C at 2 minutes
