Description
The INA193INA198 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 INA19x 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 INA193INA195 devices provide identical functions but alternative pin configurations to the INA196INA198 devices, respectively.
The INA193INA198 devices operate from a single 2.7-V to 18-V supply, drawing a maximum of 900 µA of supply current. They are specified over the extended operating temperature range (40°C to +125°C), and are offered in a space-saving SOT-23 package.
Same functionality and pinout but is not an equivalent to the compared device:
