Figure 4. Typical Application Circuit
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
vides two SCL cycles (t
hold capacitance must acquire a charge representing
the input signal. Minimize the input source impedance
