Active-Low End of Conversion Output. EOC goes low when conversion is
completed. EOC goes high when a conversion is initiated.
Convert Start Input. Rising edge of CONVST ends sample and starts a
conversion on the captured sample. The ADC is in acquisition mode when
CONVST is low and CONVST mode = 0.
Shutdown Input. If SHDN is held high, the entire device enters and stays in a
low-current state. Contents of the Configuration register are not lost when in
the shutdown state.
Reference Buffer Decoupling. Connect all RDC outputs together. Bypass to
AGND with at least an 80µF total capacitance. See the Layout, Grounding,
and Bypassing section.
Signal Ground. Connect all AGND and AGNDS inputs together on PWB.
