3 Description
The INA19xA-Q1 family of current shunt monitors
with voltage output can sense drops across shunts at
common-mode voltages from –16 V to 80 V,
independent of the INA19xA supply voltage. They are
available with three output voltage scales: 20 V/V,
50 V/V, and 100 V/V. The 500-kHz bandwidth
simplifies use in current control loops and monitoring
DC motor health. The INA193A–INA195A provide
identical functions but alternative pin configurations to
the INA196A–INA198A, respectively.
The INA19xA-Q1 operate from a single 2.7-V to 18-V
supply. They are specified over the extended
operating temperature range (–40°C to 125°C), and
are offered in a space-saving SOT-23 package.
