Note 1:
Intermodulation distortion is the total power of the intermodulation products relative to the total input power.
Note 2:
REFP, REFN, and COM should be bypassed to GND with a 0.1μF (min) or 1μF (typ) capacitor.
Note 3:
Digital outputs settle to V
IH
, V
IL
. Parameter guaranteed by design.
Note 4:
With REFIN driven externally, REFP, COM, and REFN are left floating while powered down.
Note 5:
Amplitude matching is measured by applying the same signal to each channel and comparing the magnitude of the funda-
mental of the calculated FFT. The data from both ADC channels must be captured simultaneously during this test.
Note 6:
Phase matching is measured by applying the same signal to each channel and comparing the phase of the fundamental of
the calculated FFT. The data from both ADC channels must be captured simultaneously during this test.
