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.
