INA190A1QDDFRQ1 TI Current Regulation/Management
The INA190A1QDDFRQ1 is an automotive-grade (AEC-Q100) low-power, voltage-output current-sense amplifier from Texas Instruments featuring a fixed gain of 25 V/V and ultra-low input bias current. It operates over a single supply 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 and provides exceptional DC precision. Housed in an 8-pin SOT-23-THN (DDF) package, it operates over -40°C to 125°C. Applications include load current measurement in automotive electronics, battery monitoring, overcurrent protection, and power management.
