11.1.2 Anti-kickback circuitry
11.1.3 Transformer
Anti-kickback circuitry (RC filter in
charge injection generated by the sampling capacitance.
The RC filter is also used to filter noise from the signal before it reaches the sampling
stage. The value of the capacitor should be chosen to maximize noise attenuation without
degrading the settling time excessively.
The component values are determined by the input frequency and should be selected so
as not to affect the input bandwidth.
Table 9.
The configuration of the transformer circuit is determined by the input frequency. The
configuration shown in
