PARAMETERS
DIGITAL OUTPUT CHARACTERISTICS
SUPPLY CHARACTERISTICS
Min/max ratings are based on product characterization and simulation. Individual parameters are tested as noted. Outgoing quality levels are
determined from tested parameters.

positive supply voltage
differential voltage between any two grounds
analog input voltage range
digital input voltage range
output short circuit duration (one-pin to ground)
junction temperature
storage temperature range
lead solder duration (+240°C)
Note: Absolute maximum ratings are limiting values, to be applied individually, and
beyond which the serviceability of the circuit may be impaired. Functional
operability under any of these conditions is not necessarily implied. Exposure to
maximum ratings for extended periods may affect device reliability.

These parameters are 100% tested at 25°C .
Harmonics and clock spurious are removed in noise
measurements.
4th or higher harmonic.
Low frequency dither injected in the DC to 500KHz band.
Next worst clock spur is a subharmonic of fs, but not fs/8 or fs/4.
See text on spurious.
