DESCRIPTIONThe XTR101 is a microcircuit, 4-20mA, two-wire
transmitter containing a high accuracy instrumentation
amplifier (IA), a voltage-controlled output current source,
and dual-matched precision current reference. This
combination is ideally suited for remote signal conditioning
of a wide variety of transducers such as thermocouples,
RTDs, thermistors, and strain gauge bridges. State-of-the-
art design and laser-trimming, wide temperature range
operation, and small size make it very suitable for
industrial process control applications. In addition, the
optional external transistor allows even higher precision.
The two-wire transmitter allows signal and power to be
supplied on a single wire pair by modulating the
power-supply current with the input signal source. The
transmitter is immune to voltage drops from long runs and
noise from motors, relays, actuators, switches,
transformers, and industrial equipment. It can be used by
OEMs producing transmitter modules or by data
acquisition system manufacturers.
