INA190/INA190-Q1 Current-Shunt Monitors

Texas Instruments INA190/INA190-Q1 Current-Shunt Monitors provide overcurrent protection and precision current measurement for system optimization or in closed-loop feedback circuits. These voltage-output monitors can sense drops across shunts at common-mode voltages from –0.2V to +40V, independent of the supply voltage. The INA190/INA190-Q1 features five fixed gain options of 25V/V, 50V/V, 100V/V, 200V/V, or 500V/V. The INA190/INA190-Q1 offers a low input bias current, permitting the use of larger current-sense resistors. This allows accurate, current measurements in the microamp range.
