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
58.6ksps, 14-Bit, 2-Wire Serial ADC
in a 14-Pin TSSOP
