PRODUCTION DATA
PIN | I/O | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
ADDR | D4 | I | Address detect pin. Resistor value at this pin selects the I2C address. See Section 8.3.1. Minimize capacitive loading on this pin and do not connect to any other load. |
AVDD | E5 | P | Analog power input. Connect to 1.8V supply and decouple to GND with a capacitor. |
BST_N | A2 | P | Class-D negative bootstrap. Connect a capacitor between BST_N and OUT_N. |
BST_P | B2 | P | Class-D positive bootstrap. Connect a capacitor between BST_P and OUT_P. |
DREG | C2 | P | Digital core voltage regulator output. Bypass to GND with a capacitor. Do not connect to external load. |
FSYNC | D2 | I | TDM Frame Sync. |
GND | E4 | P | Analog ground. Connect to PCB ground plane. |
C1 | |||
ICC | F5 | IO | Interchip communication pin used to transmit gain alignment. |
IOVDD | F3 | P | Digital IO Supply. Connect to 1.2V or 1.8 V supply and decouple with a capacitor to GND. |
IRQZ | E3 | O | Open drain, active low interrupt pin. Pull up to IOVDD with resistor if optional internal pull up is not used. |
BYP_EN | D3 | O | Low voltage signaling pin with open drain output. It can be used to enable/disable an external converter. |
