• Power Management

• Three Transfer Functions Available:

• Battery Chargers

20 V/V, 50 V/V, and 100 V/V

• Complete Current-Sense Solution

The INA193A–INA198A 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. The INA193A–INA195A provide identical functions but alternative pin configurations to the

INA196A–INA198A, respectively.

The INA193A–INA198A 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.
