Power Down input. When this pin is high, the converter is
in the Power Down mode and the data output pins hold
the last conversion result.
CMOS/TTL compatible digital clock Input. V
on the falling edge of CLK input.
Conversion data digital Output pins. D0 is the LSB, D7 is
the MSB. Valid data is output just after the rising edge of
the CLK input.
Reference ground for the single-ended analog input, V
Positive analog supply pin. Connect to a clean, quiet
voltage source of +3V. V
µF ceramic chip capacitor for each pin, plus one
10 µF capacitor. See Section 3.0 for more information.
Power supply for the output drivers. If connected to V
decouple well from V
The ground return for the output driver supply.
The ground return for the analog supply.
