1 2 N.C. No Connect. Connect to ground plane for better thermal performance to the PC board.
2 1 GND Ground
3 3 V
CC
Supply Voltage Input. Bypass V
CC
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.
4 4 SCK Serial Clock Input
5 5 CS
Chip-Select Input. Enables the interface. A rising edge off CS initiates the next conversion.
Pulling CS low initiates an idle state.
6 6 SO Serial Data Output
— — EP Exposed Pad (TDFN only). Connect to GND or leave unconnected.
