Positive supply pin. These pins should be connected to a quiet +2.7V to +5.5V source and
bypassed to GND with 0.1 μF and 1 μF monolithic capacitors located within 1 cm of the
power pin.
Ground reference for CMOS circuitry. DAP is the exposed metal contact at the bottom of the
LLP package. The DAP is used as the primary GND connection to the device. It should be
connected to the ground plane with at least 4 vias for optimal low-noise and thermal
performance.
(Note 1)
GND
Note 1:
Note that GND is not an actual pin on the package, the GND is connected thru the DAP on the back side of the LLP package.
