3.2 Analog input specification
Maximum input voltage:
- When R1 (470ohm) is inserted, the absolute value of the input voltage should be
less than 5V.
- When the absolute value is higher than 5V, R1(Kohm) = 2Vi-10 should be inserted.
The
µ
P reads always +5V.
Resolution of the digital conversion: 11 bit full scale.
Typical offset: 5 bits
