DESCRIPTION
The XTR300 is a complete output driver for industrial
and process control applications. The output can be
configured as current or voltage by the digital I/V
select pin. No external shunt resistor is required. Only
external gain-setting resistors and a loop
compensation capacitor are required.
The separate driver and receiver channels provide
flexibility. The Instrumentation Amplifier (IA) can be
used for remote voltage sense or as a high-voltage,
high-impedance measurement channel. In voltage
output mode, a copy of the output current is provided,
allowing calculation of load resistance.
The digital output selection capability, together with
the error flags and monitor pins, make remote
configuration and troubleshooting possible. Fault
conditions on the output and on the IA input as well
as over-temperature conditions are indicated by the
error flags. The monitoring pins provide continuous
feedback about load power or impedance. For
additional protection, the maximum output current is
limited and thermal protection is provided.
The XTR300 is specified over the −40°C to +85°C
industrial temperature range and for supply voltages
up to 40V.
