CURRENT SHUNT MONITORS
– 16-V to +80-V Common-Mode Range
• Welding Equipment
• Qualified for Automotive Applications
• Notebook Computers
• Wide Common-Mode Voltage:
• Cell Phones
– 16 V to +80 V
• Telecom Equipment
• Low Error: 3.0% Over Temperature (Max)
• Automotive
• Bandwidth: Up to 500 kHz
• 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.
