1: The above condition represents 1ch.
2: The above conditions distortion rate of 1-Ach and dynamic range measurement.
3: SW5 is for residual noise measurement.
4: SW8 is for cross talk (ISO or SEP) measurement.
SUPPLY CURRENT (FIGURE 1)
VCC
A
This current is a consumption current with a nonloading
condition.
1) Bias supply to Pins 2,4,9,11. (This condition is the same
with other measurements, omitted from the next for
simplicity)
2) Measure the inflow current to Pin 1 from VCC. This current is
the supply current.
