VDD must be connected to the common VDD voltage VDD A4 20 P supply. Decouple to GND (pin 19 on the QFN) with its own 1 µF capacitor. Charge pump ground. GND must be connected to common supply GND. It is GND A3 19 P recommended that this pin be decoupled to the VDD of the charge pump pin (pin 20 on the QFN). Charge pump flying capacitor positive terminal. Connect one side of the flying capacitor CPP A2 18 P to CPP. Charge pump flying capacitor negative terminal. Connect one side of the flying capacitor CPN A1 17 P to CPN. Left channel negative differential input. Impedance must be matched to LEFTINP. LEFTINM B4 1 I Connect the left input to LEFTINM when using single-ended inputs. Left channel positive differential input. Impedance must be matched to LEFTINM. AC LEFTINP B3 2 I ground LEFTINP near signal source while maintaining matched impedance to LEFTINM when using single-ended inputs. Negative supply generated by the charge pump. Decouple to pin 19 on the QFN or a CPVSS B2 15, 16 P GND plane. Use a 1 µF capacitor. HPLEFT B1 14 O Headphone left channel output. Connect to left terminal of headphone jack. Right channel negative differential input. Impedance must be matched to RIGHTINP. RIGHTINM C4 5 I Connect the right input to RIGHTINM when using single-ended inputs. Right channel positive differential input. Impedance must be matched to RIGHTINM. AC RIGHTINP C3 4 I ground RIGHTINP near signal source while maintaining matched impedance to RIGHTINM when using single-ended inputs. Analog ground. Must be connected to common supply GND. It is recommended that this 3, 9, 10, GND C2 P pin be used to decouple VDD for analog. Use pin 13 to decouple pin 12 on the QFN 13 package. Analog VDD. VDD must be connected to common VDD supply. Decouple with its own VDD C1 12 P 1- µF capacitor to analog ground (pin 13 on the QFN). SD D4 6 I Shutdown. Active low logic. 5V tolerant input. SDA D3 7 I/O SDA - I2C Data. 5V tolerant input. SCL D2 8 I SCL - I2C Clock. 5V tolerant input. HPRIGHT D1 11 O Headphone light channel output. Connect to the right terminal of the headphone jack. Thermal Solder the thermal pad on the bottom of the QFN package to the GND plane of the N/A Die Pad P pad PCB. It is required for mechanical stability and will enhance thermal performance. 3 |
