3 Description
The INA199-Q1 family is a series of voltage-output,
current-sense amplifiers that can sense drops across
shunts at common-mode voltages from –0.1 V to
26 V, independent of the supply voltage. Three fixed
gains are available: 50 V/V, 100 V/V, and 200 V/V.
The low offset of the zero-drift architecture enables
current sensing with maximum drops across the
shunt as low as 10-mV full-scale.
These devices operate from a single 2.7-V to 26-V
power supply, drawing a maximum of 100 μA of
supply current. All versions are specified from –40°C
to +125°C, and are offered in a 6-pin SC70 package.
