Note 1: This applies when using one D-A converter, with the D-A register for the unused D-A converter set to
“00
16
”.
The A-D converter's ladder resistance is not included.
Also, when D-A register contents are not “00
16
”, the current I
VREF
always flows even though Vref may
have been set to be unconnected by the A-D control register.
Note 2: Specify a product of -40°C to 85°C to use it.

Note 1: Do f(X
IN
) in range of main clock input oscillation frequency prescribed with recommended operating
conditions of table 1.23.2. Divide the f
AD
if f(X
IN
) exceeds 10MHz, and make AD operation clock frequency
(AD) equal to or lower than 10MHz. And divide the f
AD
if V
CC
is less than 4.2V, and make AD operation
clock frequency (AD) equal to or lower than f
AD
/2.
Note 2: A case without sample & hold function turn AD operation clock frequency (AD) into 250 kHz or more in
addition to a limit of Note 1.
A case with sample & hold function turn AD operation clock frequency (AD) into 1MHz or more in addition
to a limit of Note 1.
Note 3: Connect AV
CC
pin to V

pin and apply the same electric potential.
Note 4: Specify a product of -40°C to 85°C to use it.
