INA190 - Precision Current-Sense Amplifier

General Description

The INA190 is a low-power, voltage-output, currentshunt monitor (also called a current-sense amplifier).

This device is commonly used for overcurrent protection, precision current measurement for system optimization, or in closed-loop feedback circuits.

Key Features

  • 1 Low input bias currents: 500 pA (typ) (enables microamp current measurement).
  • Low power:.
  • Low supply voltage, VS: 1.7 V to 5.5 V.
  • Low shutdown current: 100 nA (max).
  • Low quiescent current: 50 μA at 25°C (typ).
  • Accuracy:.
  • Common-mode rejection ratio: 132 dB (min).
  • Gain error: ±0.2% (A1 device).
  • Gain drift: 7 ppm/°C (max).
  • Offset voltage, VOS: ±15 μV (max).
  • Offset drift: 80 nV/°C (max).
  • Wi.
