Analog inputs. These signals can range from 0V to V
Digital clock input. This clock directly controls the conversion and readout processes.
Digital data output. The output samples are clocked out of this pin on falling edges of the
SCLK pin.
Digital data input. The ADC104S021'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 supply pin. This pin should be connected to a quiet +2.7V to +5.25V source and
bypassed to GND with a 1 µF capacitor and a 0.1 µF monolithic capacitor located within
1 cm of the power pin.
The ground return for supply and signals.
