Introduction

AI Translation

The INA190 is a low-power, voltage-output, current shunt monitor (also known as a current sense amplifier). This device is commonly used in overcurrent protection, precision current measurement for system optimization, or closed-loop feedback circuits. The INA190 measures the voltage drop across a shunt resistor at common-mode voltages ranging from -0.2V to +40V, independent of the supply voltage. The device's low input bias current allows the use of larger current sense resistors, enabling precise current measurements at the microampere level. The zero-drift architecture's low offset voltage extends the dynamic range of current measurement. This feature supports smaller sense resistors while maintaining precise current measurement with lower power loss. The INA190 operates from a single 1.7V to 5.5V supply, consuming a maximum supply current of 65μA when enabled and only 0.1μA when disabled. Five fixed gain options are available: 25V/V, 50V/V, 100V/V, 200V/V, or 500V/V. The device is rated for an operating temperature range of -40°C to +125°C and is available in UQFN, SC70, and SOT-23 packages.
