The thermal pad can be connected to the analog ground or left floating. Keep the thermal pad separate from the digital ground, if possible. PIN ASSIGNMENTS PIN NO. PIN QFN WCSP NAME I/O A/D DESCRIPTION 1 D1 SDA I/O D Serial data I/O 2 C1 SCL I D Serial clock. 3 B2 AD1 I D Address input bit 1 4 A1 PINTDAV O D Interrupt output. Data available or PENIRQ, depending on setting. Pin polarity with active low. 5 B1 RESET I D System reset. All register values reset to default values. 6 A2 DGND Digital ground 7 A3 I/OVDD Digital I/O interface voltage B3, B4, No internal connection, but solder bumps are populated. These pins may be connected to analog ground 8, 19 C2, C3, NC for mechanical stability.
