to eliminate input frequency folding

(aliasing) and to allow for the skirt response of the filter.

Note 2: Consider the amplitude errors which are introduced within the passband of the filter.

*Use ADC0801, 02, 03 or 05 for lowest power consumption.

Note: Logic inputs can be driven to V

with A/D supply at zero volts.

Buffer prevents data bus from overdriving output of A/D when in shutdown mode.
