The INA293 is a high-precision current sense
amplifier that can measure voltage drops across
shunt resistors over a wide common-mode range
from –4 V to 110 V. 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 INA293 is not only designed for
DC current measurement, but also for high-speed
applications (ex. Fast over-current protection) with a
high bandwidth of 1.3 MHz and an 85-dB AC CMRR
(at 50 kHz).
The INA293 operates from a single 2.7-V to 20-V
supply, drawing 1.5 mA of supply current. The
INA293 is available with five gain options: 20 V/V, 50
V/V, 100 V/V, 200 V/V, and 500 V/V. These gain
options address wide dynamic range current-sensing
applications.INA293A1IDBVR
