INA180 Current-Sense Amplifiers

Texas Instruments offers their INA180 26 V, 350 kHz bandwidth, low- or high-side voltage output current sense amplifiers

Image of Texas Instruments' INA180 Current Sense AmplifiersTexas Instruments' INA180 is a family of cost-optimized, current-sense amplifiers (also called current-shunt monitors) that sense voltage drops across current-sense resistors at common-mode voltages from -0.2 V to +26 V, independent of the supply voltage. The INA180 integrates a matched resistor gain network in four fixed-gain device options: 20 V/V, 50 V/V, 100 V/V, or 200 V/V. This matched gain resistor network minimizes gain error and reduces the temperature drift.

The INA180 operates from a single 2.7 V to 5.5 V power supply, drawing a maximum of 260 µA of supply current.

All device options are specified over the extended operating temperature range of -40°C to +125°C and are available in a 5-pin, SOT-23 package with two different pin configurations.

  • Common-mode range (VCM): -0.2 V to +26 V
  • Offset voltage:
    • ±150 µV (max) at VCM = 0 V
    • ±500 µV (max) at VCM = 12 V
  • Output slew rate: 2 V/µs
  • Accuracy:
    • ±1% gain error (max)
    • 1 µV/°C offset drift (max)
