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
will enter and stay in a low-current state. Contents of
the configuration register are not lost when in the
shutdown mode.
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.
