INA195

INA193, INA194 INA195, INA196 INA197, INA198 SBOS307B − MAY 2004 − REVISED JUNE 2004 CURRENT SHUNT MONITOR −16V to 36V Common-Mode Range FEATURES D WIDE COMMON-MODE VOLTAGE: D D D D D −16V to 36V LOW ERROR: 3.0% Over Temp (max) BANDWIDTH: Up to 500kHz THREE TRANSFER FUNCTIONS AVAILABLE: 20V/V, 50V/V, and 100V/V QUIESCENT CURRENT: 900µA (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 +36V, 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 +13.5V supply, drawing a maximum of 900µA 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.
