XTR101

SBOS146A − OCTOBER 1986 − REVISED AUGUST 2004

Precision, Low Drift

4-20mA TWO-WIRE TRANSMITTER

F_DEATURES

DESCRIPTION

INSTRUMENTATION AMPLIFIER INPUT:

− Low Offset Voltage, 30µV max

− Low Voltage Drift, 0.75µV/°C max

− Low Nonlinearity, 0.01% max

The 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.

TRUE TWO-WIRE OPERATION:

− Power and Signal on One Wire Pair

− Current Mode Signal Transmission

− High Noise Immunity

DUAL MATCHED CURRENT SOURCES

WIDE SUPPLY RANGE: 11.6V to 40V

SPECIFICATION RANGE: −40°C to +85°C

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.
