IN1 and IN2
Analog inputs. These signals can range from 0V to V
A

SCLK
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 ADC082S021’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.

A
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.
