The INA293-Q1 is a versatile, automotive, high-voltage, unidirectional, voltage-output,current-sense amplifier that senses voltage drops across external sense (shunt) resistors over awide common-mode voltage range from –4 V to 110 V. The negative common-mode voltage allows thedevice to operate below ground, thus accommodating the precise measurement of a recirculatingcurrent in typical
h-bridge applications. The INA293-Q1 amplifier has a bandwidth of 1 MHz at gain of 20 V/V.The 1-MHz bandwidth in combination with a low offset of < 200 uV (max) provides fast settlingresponse with accurate measurements in a large common-mode switching transients.

The INA293-Q1 operates from a single 2.7-V to 20-V supply, drawing 1.5 mA of supplycurrent. The INA293-Q1 is available with five gain options: 20 V/V, 50 V/V, 100 V/V, 200 V/V, and500 V/V. These gain options address wide dynamic current-sensing applications.

The INA293-Q1 is specified over the operating temperature range of −40°C to +125°C, andis offered in a space-saving SOT-23 package.
