APPLICATION INFORMATION
simplified analog input analysis
Using the equivalent circuit in Figure 17, the time required to charge the analog input capacitance from 0 to VS
within 1/2 LSB can be derived as follows:
The capacitance charging voltage is given by
VC = VS 1e
t c/RtCi
(
)
(1)
where
Rt = Rs + ri
The final voltage to 1/2 LSB is given by
(2)
VC (1/2 LSB) = VS (VS/2048)
Equating equation 1 to equation 2 and solving for time tc gives
VS (VS/2048) = VS 1e
(
)
(3)
t c/RtCi
and
tc (1/2 LSB) = Rt × Ci × ln(2048)
(4)
Therefore, with the values given the time for the analog input signal to settle is
(5)
tc (1/2 LSB) = (Rs + 1 k) × 60 pF × ln(2048)
This time must be less than the converter sample time shown in the timing diagrams.

VI = Input Voltage at A0 A10
VS = External Driving Source Voltage
Rs = Source Resistance
ri = Input Resistance
Ci = Equivalent Input Capacitance
Driving source requirements:
Noise and distortion for the source must be equivalent to the
resolution of the converter.
Rs must be real at the input frequency.
