By measuring voltage at the maximum input for
approximately 500µs under the counter clock of
8MHz,resolution of approximately 12bits can be obtained;

OPERATING DESCRIPTION
(1)Decoder
.
(2)A-D conversion
Based on digital inputs to C0,C1,C2,the analog switch
is set to on,and the input of "0" scale (GND input),input
of reference scale (reference voltage input),input to
A1~A4,or discharge
.Input is selected next,obtaining input pulse T
.It then selects V
