INA190A4IDCKR TI Current Regulation/Management

The INA190A4IDCKR is a low-power, voltage-output current sense amplifier from Texas Instruments featuring a fixed gain of 200 V/V and ultra-low input bias current of 500 pA . It operates over a single supply range of 1.7V to 5.5V and draws a low quiescent current of 50 µA, with a shutdown mode reducing current to 0.1 µA . The device offers a wide common-mode voltage range of -0.2V to +40V, independent of the supply voltage, and provides exceptional DC precision with input offset voltage of ±15 µV (max), offset drift of 80 nV/°C, and CMRR of 132 dB (min) . It supports bidirectional current sensing and is available in five gain options from 25 V/V to 500 V/V . Housed in a 6-pin SC-70 (DCK) package, it operates over -40°C to 125°C . Applications include load current measurement in portable electronics, battery monitoring, overcurrent protection, power management in wearables, and automotive sensor interfaces.
