TO MICROCOMPUTER
5V POWER SUPPLY
Resolution depends on the number of microcomputer
counter clock pulses that are generated while the INT
output status is "high" at the maximum input voltage 2.5V
(vcc-2.5V).
When the microcomputer counter clock frequency is
8MHz,the resolution can be calculated by using the
constant calculated above,as follows;
Therefore,the resolution of this system is approximately
11 bits.
