INA193-INA198 is a voltage output current shunt monitor that 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. INA193-INA195 provide identical functions but alternative pin configurations to the INA196-INA198, respectively. INA193-INA198 operate from a single +2.7V to +18V 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.
The INA193‑INA198 family of current shunt monitors provides a wide common‑mode voltage range (‑16 V to +80 V) and selectable gain options of 20 V/V, 50 V/V, or 100 V/V. They operate from a single +2.7 V to +18 V supply and draw a low quiescent current, making them suitable for power‑management and current‑control applications.
Typical applications include notebook computers, cell phones, automotive systems, and battery chargers. The datasheet includes absolute maximum ratings, package information, pin assignments, electrical characteristics, typical performance curves, and mechanical dimensions.
