WITH NO
No Connect. Connect to ground plane for better thermal performance to the PC board.
Ground
Supply Voltage Input. Bypass V
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.
Serial Clock Input
Chip-Select Input. Enables the interface. A rising edge off CS initiates the next conversion.
Pulling CS low initiates an idle state.
