DESCRIPTION
The INA210, INA211, INA212, INA213, and INA214
are voltage output current shunt monitors that can
sense drops across shunts at common-mode
voltages from –0.3V to 26V, independent of the
supply voltage. Five fixed gains are available: 50V/V,
100V/V, 200V/V, 500V/V, or 1000V/V. The low offset
of the Zerø-Drift architecture enables current sensing
with maximum drops across the shunt as low as
10mV full-scale.
These devices operate from a single +2.7V to +26V
power supply, drawing a maximum of 100μA of
supply current. All versions are specified over the
extended operating temperature range (–40°C to
+125°C), and offered in an SC70 package. The
INA210, INA213, and INA214 are also offered in a
thin QFN package.
