INA281A2IDBVR TI Current Regulation/Management
The INA281A2IDBVR is a high-precision, voltage-output current-sense amplifier from Texas Instruments featuring a fixed gain of 50 V/V and a wide common-mode range of -4V to +110V. It operates over a single supply range of 2.7V to 20V and draws a low quiescent current of 450 µA. The device provides low offset voltage, low gain error, and enhanced PWM rejection for accurate current measurement in switching systems. Housed in a 5-pin SOT-23 (DBV) package, it operates over -40°C to 125°C. Applications include overcurrent protection, battery monitoring, load current measurement in industrial systems, motor drives, and power management in telecommunications.
