INA225AIDGKR +BOM

36V, bi-directional current sense amplifier w/ four pin-selectable gain settings

INA225AIDGKR General Description

One of the key highlights of the INA225AIDGKR is its ability to select from four different gain levels using gain-select terminals. By choosing between gains of 25 V/V, 50 V/V, 100 V/V, and 200 V/V, users can customize the amplifier to suit their specific application requirements. This flexibility, combined with the device's low-offset, zero-drift architecture, ensures precise current-sensing with minimal voltage drops across the shunt

Key Features

  • Wide Common-Mode Range: 0 V to 36 V
  • Offset Voltage: ±150 µV (Max, All Gains)
  • Offset Voltage Drift: 0.5 µV/°C (Max)
  • Gain Accuracy, Over Temperature (Max):
    • 25 V/V, 50 V/V: ±0.15%
    • 100 V/V: ±0.2%
    • 200 V/V: ±0.3%
    • 10-ppm/°C Gain Drift
  • 250-kHz Bandwidth (Gain = 25 V/V)
  • Programmable Gains:
    • G1 = 25 V/V
    • G2 = 50 V/V
    • G3 = 100 V/V
    • G4 = 200 V/V
  • Quiescent Current: 350 µA (Max)
  • Package: MSOP-8
