Spurious-Free Dynamic Range (SFDR)
1
The difference in dB between the rms amplitude of the input
signal and the peak spurious signal.
Temp eratur e Drift
The temperature drift for offset error and gain error specifies
the maximum change from initial (25°C) value to the value at
T
MIN
or T
MAX
.
Total Harmonic Distortion (THD)
1
The ratio of the rms sum of the first six harmonic components
to the rms value of the measured input signal.
Offset Error
The major carry transition should occur for an analog value
½ LSB below VIN+ = VIN−. Offset error is defined as the
deviation of the actual transition from that point.
1
AC specifications can be reported in dBc (degrades as signal levels are
lowered) or in dBFS (always related back to converter full scale).
