M
forming a digital representation of the analog input sig-
nal. During the conversion period, the MAX1069 holds
SCL low (clock stretching).
The time required for the T/H to acquire an input signal
is a function of the analog input source impedance. If
the input signal source impedance is high, lengthen the
acquisition time by reducing f
SCL
. The MAX1069 pro-
vides two SCL cycles (t
ACQ
), in which the track-and-
hold capacitance must acquire a charge representing
the input signal. Minimize the input source impedance
(R
SOURCE
) to allow the track-and-hold capacitance to
charge within the allotted time. R
SOURCE
should be
less than 12.9k
