TYPICAL APPLICATIONS (continued)
(1) Oversample whenever possible [keep fs > 2f(−60)] to eliminate input frequency folding (aliasing) and to allow for the
skirt response of the filter.
(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
CC
with A/D supply at zero volts.
Buffer prevents data bus from overdriving output of A/D when in shutdown mode.
