The INA951-SEP is a current sense amplifier that can measure voltage drops across shunt resistors over a wide common-mode range from –4V to 80V. The negative common-mode voltage allows the device to operate below ground, thus accommodating precise measurement of recirculating currents in half-bridge applications. The combination of a low offset voltage, small gain error and high DC CMRR enables highly accurate current measurement. The INA951-SEP is not only designed for DC current measurement, but also for high-speed applications (ex. Fast over-current protection) with a high bandwidth of 1.3MHz and an 85dB AC CMRR (at 50kHz).
The INA951-SEP operates from a single 2.7V to 10V supply, drawing 1.5mA of supply current. The INA951-SEP is available with a gain option of 20V/V.
The INA951-SEP is specified over an operating temperature range of −55°C to +125°C and is offered in a space-saving SOT-23 package.
