NO. (I/O/P) Charge pump voltage supply. VDD must be connected to the common VDD voltage supply. Decouple VDD A4 20 P 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 recommended that this GND A3 19 P pin be decoupled to the VDD of the charge pump pin (pin 20 on the QFN). CPP A2 18 P Charge pump flying capacitor positive terminal. Connect one side of the flying capacitor to CPP. CPN A1 17 P Charge pump flying capacitor negative terminal. Connect one side of the flying capacitor to CPN. Left channel negative differential input. Impedance must be matched to LEFTINP. Connect the left LEFTINM B4 1 I input to LEFTINM when using single-ended inputs. Left channel positive differential input. Impedance must be matched to LEFTINM. AC ground LEFTINP B3 2 I 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 GND plane. CPVSS B2 15, 16 P 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. Connect the RIGHTINM C4 5 I right input to RIGHTINM when using single-ended inputs. Right channel positive differential input. Impedance must be matched to RIGHTINM. AC ground RIGHTINP C3 4 I 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 pin be used GND C2 3, 9, 10, 13 P to decouple VDD for analog. Use pin 13 to decouple pin 12 on the QFN package. Analog VDD. VDD must be connected to common VDD supply. Decouple with its own 1-μF capacitor to VDD C1 12 P 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. Solder the thermal pad on the bottom of the QFN package to the GND plane of the PCB. It is Thermal pad N/A Die Pad P required for mechanical stability and will enhance thermal performance. 4 Submit Documentation Feedback Copyright © 2006–2015, Texas Instruments Incorporated Product Folder Links: TPA6130A2 |
