Analog inputs. These signals can range from 0V to V
Digital clock input. The guaranteed performance range of frequencies for this input is 0.8
MHz to 3.2 MHz. This clock directly controls the conversion and readout processes.
Digital data output. The output samples are clocked out of this pin on the falling edges of
the SCLK pin.
Digital data input. The ADC108S022's Control Register is loaded through this pin on rising
edges of the SCLK pin.
Chip select. On the falling edge of CS, a conversion process begins. Conversions
continue as long as CS is held low.
Positive analog supply pin. This voltage is also used as the reference voltage. This pin
should be connected to a quiet +2.7V to +5.25V source and bypassed to GND with 1 µF
and 0.1 µF monolithic ceramic capacitors located within 1 cm of the power pin.
