DESCRIPTION
The XTR104 is a monolithic 4-20mA, two-wire cur-
rent transmitter integrated circuit designed for bridge
input signals. It provides complete bridge excitation,
instrumentation amplifier, linearization, and current
output circuitry necessary for high impedance strain
gage sensors.
The instrumentation amplifier can be used over a wide
range of gain, accommodating a variety of input signals
and sensors. Total adjusted error of the complete current
transmitter, including the linearized bridge is less than
±
1% over the full –40
°
C to +85
°
C temperature range.
This includes zero drift, span drift and non-linearity for
bridge outputs as low as 10mV. The XTR104 operates
on loop power supply voltages down to 9V.
Linearization circuitry consists of a second, fully inde-
pendent instrumentation amplifier that controls the bridge
excitation voltage. It provides second-order correction
to the transfer function, typically achieving a 20:1
improvement in nonlinearity, even with low cost trans-
ducers.
The XTR104 is available in 16-pin plastic DIP and
SOL-16 surface-mount packages specified for the
–40
°
C to +85
°
C temperature range.
