CURRENT SHUNT MONITOR
-16V to +80V Common-Mode Range

FEATURES
D WIDE COMMON-MODE VOLTAGE: D D D D D
-16V to +80V LOW ERROR: 3.0% Over Temp (max) BANDWIDTH: Up to 500kHz THREE TRANSFER FUNCTIONS AVAILABLE: 20V/V, 50V/V, and 100V/V QUIESCENT CURRENT: 900uA (max) COMPLETE CURRENT SENSE SOLUTION

DESCRIPTION
The INA193-INA198 family of current shunt monitors with voltage output can sense drops across shunts at common-mode voltages from -16V to +80V, independent of the INA19x supply voltage. They are available with three output voltage scales: 20V/V, 50V/V, and 100V/V. The 500kHz bandwidth simplifies use in current control loops. The INA193-INA195 provide identical functions but alternative pin configurations to the INA196-INA198, respectively. The INA193-INA198 operate from a single +2.7V to +18V supply, drawing a maximum of 900uA of supply current. They are specified over the extended operating temperature range (-40 C to +125 C), and are offered in a space-saving SOT23 package.
