edge of the encode command to the min/max voltage levels of the digital
outputs with 10 pF maximum loads.
RMS signal to rms noise with analog input signal 1 dB below full scale at
specified frequency.
ENCODE = 32 MSPS.
3rd order intermodulation measured with analog input frequencies of 2.3 MHz
and 2.4 MHz at 7 dB below full scale.
For rated performance at 40 MSPS, duty cycle of encode command should be
50% 10%.
Measured as the ratio of the change in offset voltage for a 5% change in +V

Absolute maximum ratings are limiting values to be applied individually, and
Typical thermal impedances (parts soldered to board):
beyond which the serviceability of the circuit may be impaired. Functional
operability is not necessarily implied. Exposure to absolute maximum rating
conditions for an extended period of time may affect device reliability.
