Applications Information
Digital Current Sensing
As shown in Figure 16, using the Isolated 2-chip A/D
converter to sense current can be as simple as connect-
ing a current-sensing resistor, or shunt, to the input and
reading output data through the 3-wire serial output
interface. By choosing the appropriate shunt resistance,
any range of current can be monitored, from less than 1
A to more than 100 A.

Even better performance can be achieved by fully utiliz-
ing the more advanced features of the Isolated A/D con-
verter, such as the pre-trigger circuit, which can reduce
conversion time to less than 1µs, the fast over-range
detector for quickly detecting short circuits, different
conversion modes giving various resolution/speed
trade-offs, offset calibration mode to eliminate initial
offset from measurements, and an adjustable threshold
detector for detecting non-short circuit overload condi-
tions.
