CC
Supply Voltage Input. Bypass V

to GND with a 0.1µF capacitor. V
CC
can also be
powered from a logic output as long as the voltage level is greater than 3.0V and the logic
output is not noisy. Setting the logic output low provides a hardware shutdown mode.

CS
Chip-Select Input. Enables the interface. A rising edge off
CS initiates the next conversion.
Pulling
CS low initiates an idle state.
