NOTES:
1. Referenced to VCC = AVCC = VREF = 3.3 to 5.5V, VSS = AVSS = 0V, –40 to 85°C unless otherwise specified.
2. φAD frequency must be 10MHz or less.
3. When sample & hold function is disabled, φAD frequency must be 250kHz or more in addition to a limit of NOTE 2.
When sample & hold function is enabled, φAD frequency must be 1MHz or more in addition to a limit of NOTE 2.

NOTES:
1. Referenced to VCC = AVCC = VREF = 3.3 to 5.5V, VSS = AVSS = 0V, –40 to 85°C unless otherwise specified.
2. This applies when using one D/A converter, with the DAi register (i = 0, 1) for the unused D/A converter set to “00h”.
The resistor ladder of the A/D converter is not included. Also, the current I
VREF always flows even though VREF
may have been set to be unconnected by the ADCON1 register.
