The XTR200 is a high-voltage, precision, output driver for 3-wire current or voltage systems, designed for standard industrial signal levels such as 0mA to 20mA, 4mA to 20mA, and 0V to 10V. The mode pin configures the device for either current or voltage output and eliminates the need to change external components to switch between modes. In current-output mode, the ratio between input voltage and output current is set by a single resistor, RSET. In voltage-output mode, the XTR200 has a fixed gain of 3.75V/V which is set by integrated, high-precision, thin-film, resistors.
The device integrates a low-leakage PMOS output transistor and short-circuit current protection, further reducing the need for external components. An external PNP or PMOS transistor can be used with the XTR200 to reduce on-chip power dissipation. The on-chip short-circuit protection also protects external transistors from damaging overcurrent events.
The XTR200 error flag pin (EF) indicates several temperature or output fault conditions. The output disable pin (OD) places the output pin into a high-impedance state with very low leakage.
The XTR200 is available in a small 3mm × 2mm, 10-pin WSON surface-mount package.
