3 Description
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 currentoutput
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 highimpedance
state with very low leakage.
The XTR200 is available in a small 3mm × 2mm,
10-pin WSON surface-mount package.
