Pin Functions

PIN I/O/P(1) DESCRIPTION
NAME NO.
ADR1 12 I I2C address inputs. Each pin can detect a short to DVDD, a short to GND, a 22-kΩ connection to GND, and a 22-kΩ connection to DVDD.
ADR0 13 I
AVDD 28 P Analog power supply input. Connect directly to PVDD.
BST_N 18 P Class-D Amplifier negative bootstrap. Connect to a capacitor between BST_N and OUT_N.
BST_P 23 P Class-D Amplifier positive bootstrap. Connect to a capacitor between BST_P and OUT_P.
DVDD 11 P Digital power supply. Connect to a 3.3-V supply with external decoupling capacitor.
FAULTZ 2 O Open drain active low fault flag. Pull up on PCB with resistor to DVDD.
LRCLK 4 I TDM interface frame synchronization.
GND 10 P Ground. Connect to PCB ground plane.
29
