(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not supported.
(2) Refer to the Package Option Addendum at the end of this document for lead temperature ratings.
(3) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails must be current limited.
(4) The IS pin can source up to the output current-limit under normal operating conditions.
(5) See text in Application Section regarding safe voltage ranges and currents.

The XTR111 is a precision voltage-to-current converter designed for the standard 0mA−20mA or 4mA−20mA analog signals, and can source up to 36mA. The ratio between input voltage and output current is set by the single resistor RSET. The circuit can also be modified for voltage output.

An external P-MOSFET transistor ensures high output resistance and a broad compliance voltage range extending from 2V below the supply voltage, V_VSP, to voltages well below GND.The adjustable 3V to 15V sub-regulator output provides the supply voltage for additional circuitry.The XTR111 is available in a DFN surface-mount package.
