Overview
The XTR111AIDGQT is a precision voltage-to-current converter and transmitter produced by Texas Instruments. It is designed to handle standard 0mA to 20mA or 4mA to 20mA analog signals and can source up to 32mA. The device features a single-resistor set (RSET) to define the input voltage to output current ratio, making it versatile for various applications. It also includes an adjustable 3V to 15V subregulator output to supply additional circuitry. Available in 10-pin HVSSOP and VSON surface-mount packages, the XTR111AIDGQT is suitable for a wide range of industrial and sensor applications.

Q & A
- What is the primary function of the XTR111AIDGQT?
The XTR111AIDGQT is a precision voltage-to-current converter and transmitter designed to handle standard 0mA to 20mA or 4mA to 20mA analog signals.
- What is the range of the adjustable voltage regulator in the XTR111AIDGQT?
The adjustable voltage regulator can be set between 3V to 15V.
- What are the available package types for the XTR111AIDGQT?
The XTR111AIDGQT is available in 10-pin HVSSOP and VSON surface-mount packages.
- What is the operating temperature range of the XTR111AIDGQT?
The operating temperature range is -40°C to 125°C.
- How is the output current accuracy of the XTR111AIDGQT specified?
The output current accuracy is specified as 0.015%.
- What is the purpose of the output error flag (EF) in the XTR111AIDGQT?
The output error flag (EF) indicates if the output current cannot correctly flow, such as in cases of wire break, high load resistor, or loss of headroom for the current output.
- How does the output disable (OD) feature work in the XTR111AIDGQT?
The output disable (OD) feature controls the output, reducing output glitches during power-on and power-off. It has a 4μA internal pull-up and requires a pull-down or short to GND to activate the output.
