FUNCTION
No Connect. Connect to ground plane for better thermal performance to the PC board.
Ground
Supply Voltage Input. Bypass VCC to GND with a 0.1μF capacitor. VCC 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.
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.
Serial Data Output
Exposed Pad (TDFN only). Connect to GND or leave unconnected.
