ADR0 26 DI Sets the LSB of the I2C address to 0 if pulled to GND, to 1 if pulled to DVDD Figure 11 ADR1 20 DI Sets the second LSB of the I2C address to 0 if pulled to GND, to 1 if pulled to DVDD 10 AGND G — Ground reference for analog circuitry(2) 15 AVDD 14 P Figure 2 Power supply for internal analog circuitry Connection point for the SPK_OUTA– bootstrap capacitor which is used to create a power supply for BSTRPA– 1 P the high-side gate drive for SPK_OUTA– Connection point for the SPK_OUTA+ bootstrap capacitor which is used to create a power supply for BSTRPA+ 5 P the high-side gate drive for SPK_OUTA Figure 3 Connection point for the SPK_OUTB– bootstrap capacitor which is used to create a power supply for BSTRPB– 48 P the high-side gate drive for SPK_OUTB– Connection point for the SPK_OUTB+ bootstrap capacitor which is used to create a power supply for BSTRPB+ 44 P the high-side gate drive for SPK_OUTB+ CN 34 P Figure 15 Negative pin for capacitor connection used in the line--driver charge pump CP 32 P Figure 14 Positive pin for capacitor connection used in the line-driver charge pump CPVDD 31 P Figure 2 Power supply for charge pump circuitry CPVSS 35 P Figure 15 –3.3-V supply generated by charge pump for the DAC DAC_OUTA 13 AO Single-ended output for Channel A of the DAC Figure 8 DAC_OUTB 36 AO Single-ended output for Channel B of the DAC DGND 29 G — Ground reference for digital circuitry. Connect this pin to the system ground. DVDD 30 P Figure 2 Power supply for the internal digital circuitry Voltage regulator derived from DVDD supply for use for internal digital circuitry. This pin is provided DVDD_REG 28 P Figure 16 as a connection point for filtering capacitors for this supply and must not be used to power any external circuitry. GND 33 G — Ground pin for device. This pin should be connected to the system ground. GPIO0 18 General purpose input/output pins (GPIOx) which can be incorporated in a HybridFlow for a given purpose. Refer to documentation of target HybridFlow to determine if any of these pins are required GPIO1 19 DI/O Figure 11 by the HybridFlow and, if so, how they are to be used. In most HybridFlows, presentation of a serial audio signal, called SDOUT, is done through GPIO2. GPIO2 21 Voltage regulator derived from PVDD supply to generate the voltage required for the gate drive of GVDD_REG 8 P Figure 5 output MOSFETs. This pin is provided as a connection point for filtering capacitors for this supply and must not be used to power any external circuitry. Word select clock for the digital signal that is active on the serial port's input data line. In I2S, LJ, and LRCK/FS 25 DI/O RJ, this corresponds to the left channel and right channel boundary. In TDM mode, this corresponds Figure 12 to the frame sync boundary. MCLK 22 DI Master clock used for internal clock tree and sub-circuit and state machine clocking 3 PGND 39 G — Ground reference for power device circuitry. Connect this pin to the system ground. 46 6 7 PVDD 41 P Figure 1 Power supply for internal power circuitry 42 43 SCL 17 DI Figure 10 I2C serial control port clock SCLK 23 DI/O Figure 12 Bit clock for the digital signal that is active on the input data line of the serial data port SDA 16 DI/O Figure 9 I2C serial control port data SDIN 24 D1 Figure 12 Data line to the serial data port SPK_INA– 11 AI Negative pin for differential speaker amplifier input A SPK_INA+ 12 AI Positive pin for differential speaker amplifier input A Figure 7 SPK_INB– 38 AI Negative pin for differential speaker amplifier input B SPK_INB+ 37 AI Positive pin for differential speaker amplifier input B (1) AI = Analog input, AO = Analog output, DI = Digital Input, DO = Digital Output, DI/O = Digital Bi-directional (input and output), P = Power, G = Ground (0 V) (2) This pin should be connected to the system ground. 4 Submit Documentation Feedback Copyright © 2014–2015, Texas Instruments Incorporated Product Folder Links: TAS5756M |
