Overview
The INA193AMDBVREP, produced by Texas Instruments, is a high-performance current shunt monitor with a voltage output. This device is designed to sense voltage drops across shunts at common-mode voltages ranging from –16 V to 80 V, independent of the supply voltage. It operates from a single 2.7-V to 18-V supply and is specified over an extended operating temperature range of –55°C to 125°C. The INA193A series, including the INA193AMDBVREP, is offered in a space-saving SOT23 package, making it ideal for various applications requiring precise current monitoring.
