DESCRIPTIONThe XTR108 is a “smart,” programmable, 4-20mA, two-wire
transmitter designed for temperature and bridge sensors.
Zero, span, and linearization errors in the analog signal
path can be calibrated via a standard digital serial interface,
eliminating manual trimming. Non-volatile external EEPROM
stores calibration settings.
The all-analog signal path contains an input multiplexer,
autozeroed programmable-gain instrumentation amplifier, dual
programmable current sources, linearization circuit, voltage
reference, sub-regulator, internal oscillator, control logic, and
an output current amplifier. Programmable level shifting
compensates for sensor DC offsets. Selectable
up- and down-scale output indicates out-of-range and burn-
out per NAMUR NE43. Automatic reset is initiated when
supply is lost.
Current sources, steered through the multiplexer, can be
used to directly excite RTD temperature sensors, pressure
bridges, or other transducers. An uncommitted op amp can
be used to convert current into a voltage. The XTR108 is
specified for –40°C to +85°C.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
