TPA183 - Precision Current Sense Amplifier

General Description

The TPA183 series of zero-drift, unidirectional current sense amplifiers can sense voltage drops across shunts at common-mode voltages from 2.7 V to 30 V.

The TPA183 series supports a voltage output with options of four fixed gains: 25 V/V, 50 V/V, 100 V/V, and 200 V/V.

Key Features

  • Offset Voltage: ±250 μV (MAX).
  • Wide Common-Mode Voltage: 2.7 V to 30 V.
  • Accuracy and Zero-Drift Performance.
  • ±1% Gain Error (Max over temperature).
  • 0.5μV/°C Offset Drift (Max).
  • 10 ppm/°C Gain Drift (Max).
  • Four Gain Options:.
  • TPA183A1: 25 V/V.
  • TPA183A2: 50 V/V.
  • TPA183A3: 100 V/V.
  • TPA183A4: 200 V/V.
  • Quiescent Current (IN+): 220 μA (Maximum).
  • Rail-to-Rail Output.
  • Package: SOT23-5.
  • Industrial.
  • 40°C to.
