Strain-Gauge Operation
Connect the differential inputs of the MAX1403 to the
bridge network of the strain gauge. In Figure 14, the
analog positive supply voltage powers the bridge net-
work and the MAX1403 along with its reference voltage.
The on-chip PGA allows the MAX1403 to handle an
analog input voltage range as low as 10mV full scale.
The differential inputs of the device allow this analog
input range to have an absolute value anywhere
between AGND and V+.
Temperature Measurement
Figure 15 shows a connection from a thermocouple to
the MAX1403. In this application, the MAX1403 is oper-
ated in its buffered mode to allow large decoupling
capacitors on the front end. These decoupling capaci-
tors eliminate any noise pickup from the thermocouple
leads. When the MAX1403 is operated in buffered
mode, it has a reduced common-mode range. In order
to place the differential voltage from the thermocouple
on a suitable common-mode voltage, the AIN2 input of
the MAX1403 is biased at the reference voltage,
+1.25V.
