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 −40°C to +125°C and is offered in a space-saving
SOT-23 package.
