Pins labeled as “not used” should be tied to ground.
Power Supplies
AGND - Analog Ground (PLCC pin 33; TQFP pin 23)
Analog supply ground pin.
AV+ - Analog Power Supply (PLCC pin 34; TQFP pin 24)
Analog supply pin for internal bandgap reference, oscillator, and timing generation circuits.
BGREF - Bandgap Reference (PLCC pin 32; TQFP pin 22)
This pin is used by the internal bandgap reference and must be connected to ground by a 4.99 kΩ ±1%
resistor to provide an internal current reference.
DGND1, DGND2, DGND3 - Digital Ground (PLCC pins 1, 18, 67; TQFP pins 57, 9, 55)
Power supply ground pins for the digital circuitry of both channels.
DV+ - Digital Power Supply (PLCC pin 68; TQFP pin 56)
Power supply pin for the digital circuitry of both channels.
