MTI1992仪表放大器可替代INA199x2

Description
The MTI199x is a voltage-output, currentsense amplifier that can sense drops across
shunts at common-mode voltages from –0.1 V
to 26V, independent of the supply voltage.
Three fixed gains are available: 50V/V, 100V/V,
and 200V/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.
This device operates from a single 2.7V to
26V power supply, drawing a maximum of 100
μA of supply current. All gain options are
specified from –40°C to +85°C, and are offered
in a 6-pin SC70 package.
