Connection Considerations
Transfer Function
If the input voltage exceeds the rail values (V
of the conversion is out of specification.
An external RC filter is sometimes added for anti-aliasing of the input signal. The R component
should be selected to ensure that the total source impedance is kept under the 10 k
mended specification. Any external components connected (via hi-impedance) to an analog
input pin (capacitor, zener diode, etc.) should have very little leakage current at the pin.
The ideal transfer function of the A/D converter is as follows: the first transition occurs when the
analog input voltage (V
