Strain Gauge
The strain gauge is an ideal application to take
advantage of the moderate bandwidth and high
accuracy of the ISL55001. The operation of the circuit
is very straightforward. As the strain variable
component resistor in the balanced bridge is subjected

to increasing strain, its resistance changes, resulting in
an imbalance in the bridge. A voltage variation from
the referenced high accuracy source is generated and
translated to the difference amplifier through the buffer
stage. This voltage difference as a function of the strain
is converted into an output voltage (see Figure 28).
