CURRENT SHUNT MONITOR
DESCRIPTIONThe INA170 is a high-side, bidirectional current shunt moni-
tor featuring a wide input common-mode voltage range, low
quiescent current, and a tiny MSOP-8 package.
Bidirectional current measurement is accomplished by out-
put offsetting. The offset voltage level is set with an external
resistor and voltage reference. This permits measurement of
a bidirectional shunt current while using a single supply for
the INA170.
Input common-mode and power-supply voltages are inde-
pendent. Input voltage can range from +2.7V to +60V on any
supply voltage from +2.7V to +40V. Low 10μA input bias
current adds minimal error to the shunt current.
The INA170 converts a differential input voltage to a current
output. This current develops a voltage across an external
load resistor, setting any gain from 1 to over 100.
The INA170 is available in an MSOP-8 package, and is
specified over the extended industrial temperature range,
–40°C to +85°C with operation from –55°C to +125°C.
