DESCRIPTION
The XTR108 is a “smart”, programmable, 4-20mA, two-
wire transmitter designed for temperature and bridge sen-
sors. Zero, span, and linearization errors in the analog
signal path can be calibrated via a standard digital serial
interface, eliminating manual trimming. Non-volatile ex-
ternal 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.
