APPLICATION INFORMATION
simplified analog input analysis
Using the equivalent circuit in Figure 2, the time required to charge the analog input capacitance from 0 V to
VS within 1/2 LSB can be derived as follows:
The capacitance charging voltage is given by
VC = VS 1–e
–tc/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 1–e
(
)
(3)
–tc/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) × 55 pF × ln(2048)
This time must be less than the converter sample time shown in the timing diagrams.
VI = Input Voltage at INPUT A0 – A10
VS = External Driving Source Voltage
Rs = Source Resistance
ri = Input Resistance
Ci = Input Capacitance
Driving source requirements:
Noise and distortion levels for the source must be at least
equivalent to the resolution of the converter.
Rs must be real at the input frequency.
