NOTES :
1. The higher voltage of 4.5 V or AVDD + 0.3 V specifies
maximum value of DVDD absolute maximum rating.
2. The VONL limits the excess voltage applied to digital
output pins.
WARNING :
Operation at or beyond these limits may result in permanent
damage to the device. Normal operating specifications are
not guaranteed at these extremes.

NOTES :
1. Specified at a 4.7 k$ AISET resistance. Use a high
precision resistor because it influences the supply
current.
2. Specified when the monitor function is off.
3. Measured when connecting 10 pF capacitors between
the DO0 to DO9 pins and GND, and inputting full scale
of 1 MHz sine wave to the ADC.
4. Measured under no analog input and with clock fixed at
low.
