TPAFE411 - HALL Sensor Signal Conditioning IC

Description

The TPAFE411 is designed only for Hall elements to use in closed-loop current-sensor modules.

The internal precision excitation circuitry for the Hall-element could effectively eliminate the offset and offset-drift of the Hall element.

Features

  • Internal Precision Voltage Reference.
  • Accuracy: 0.2% (max).
  • Temp Drift: 50ppm (max).
  • Pin Selectable for 2.5V, 1.65V, and Ratio Metric.
  • Switching Current HALL Sensor Excitation.
  • Reduce HALL Sensor Offset and Drift.
  • Reduce HALL Sensor 1/f Noise.
  • Extended Current Measurement Range.
  • H-Bridge Drive Capability: 350 mA.
  • Precision Current Sensing Amplifier.
  • Offset and Drift: 100μV and 2μV/°C (Max).
  • Bandwidth: 200kHz.
  • Overrange and Error F.
