DESCRIPTION

Uncorrected

Bridge Output

The XTR106 is a low cost, monolithic 4-20mA, two-

wire current transmitter designed for bridge sensors. It

provides complete bridge excitation (2.5V or 5V refer-

ence), instrumentation amplifier, sensor linearization,

and current output circuitry. Current for powering ad-

ditional external input circuitry is available from the

V_REGpin.

Corrected

The instrumentation amplifier can be used over a wide

range of gain, accommodating a variety of input signal

types and sensors. Total unadjusted error of the com-

plete current transmitter, including the linearized bridge,

is low enough to permit use without adjustment in many

applications. The XTR106 operates on loop power sup-

ply voltages down to 7.5V.

Linearization circuitry provides second-order correction

to the transfer function by controlling bridge excitation

voltage. It provides up to a 20:1 improvement in

nonlinearity, even with low cost transducers.

The XTR106 is available in 14-pin plastic DIP and

SO-14 surface-mount packages and is specified for the

–40°C to +85°C temperature range. Operation is from

–55°C to +125°C.
