26-V, Bi-Directional, Zero-Drift, Low- or High-Side, Voltage Output Current Shunt Monitor - INA199

INA199 (ACTIVE)

26-V, Bi-Directional, Zero-Drift, Low- or High-Side, Voltage Output Current Shunt Monitor

 

Description

The INA199 series of voltage-output, current-shunt monitors (also called current-sense amplifiers) are commonly used for overcurrent protection, precision-current measurement for system optimization, or in closed-loop feedback circuits. This series of devices can sense drops across shunt resistors at common-mode voltages from –0.3 V to 26 V, independent of the supply voltage. Three fixed gains are available: 50 V/V, 100 V/V, and 200 V/V. The low offset of the zero-drift architecture enables current sensing with maximum drops across the shunt as low as 10-mV full-scale.

These devices operate from a single 2.7-V to 26-V power supply, drawing a maximum of 100 µA of supply current. All versions are specified from –40°C to 125°C, and offered in both SC70-6 and thin UQFN-10 packages.

Features

  • Wide Common-Mode Range: –0.3 V to 26 V
  • Offset Voltage: ±150 µV (Maximum)
    (Enables Shunt Drops of 10-mV Full-Scale)
  • Accuracy:
    • Gain Error (Maximum Over Temperature):
      • ±1% (C Version)
      • ±1.5% (A and B Versions)
    • 0.5-µV/°C Offset Drift (Maximum)
    • 10-ppm/°C Gain Drift (Maximum)
  • Choice of Gains:
    • INA199x1: 50 V/V
    • INA199x2: 100 V/V
    • INA199x3: 200 V/V
  • Quiescent Current: 100 µA (Maximum)
  • Packages: 6-Pin SC70, 10-Pin UQFN
