The clock and data lines are bidirectional (open-collector) with an external chip pull-up resistor (typically 10 kΩ). The maximum clock frequency in fast-mode specified by the I2C standard is 400 kHz, and this frequency is supported by the TS4956. In this application, the TS4956 is always the slave device and the controlling MCU is the master device. The I2CVCC pin determines the power supply of the TS4956’s I2C interface. The voltage connected to this pin must be equal to or less than the TS4956 power supply voltage VCC. The minimum value of the I2CVCC voltage is 2.7 V. ) s ( ct When the I2CVCC pin is connected to an I2C voltage, the TS4956 is ready to communicate via the I2C bus. u d o When the I2CVCC pin is connected to the ground, the TS4956 is in total standby mode, with an ultra-low standby current on the order of a few nanoamperes. In this condition the TS4956 cannot receive I2C commands from the I2C bus. r P e In both cases, pins SDA and SCL must respect logic HI or logic LOW thresholds (not floating) presented in Table 3 on page 4, in order for the circuit to function properly. t e l o Table 5 summarizes the pin descriptions for the I²C bus interface.

The TS4956 is addressed by a single byte consisting of a 7-bit slave address and an R/W bit. The TS4956 control register address is $5Dh. Table 6. First byte after the START message for addressing the device A6 A5 A4 A3 A2 A1 A0 Rw 1 0 1 1 1 0 1 X In order to write data into the TS4956 control register, after the "start" message the MCU must send the following data: ● send byte with the I²C 7-bit slave address and with the R/W bit set low. ● send the data (control register setting). All bytes are sent with the MSB bit first. The transfer of written data ends with a "stop" message. When transmitting several bits of data, the data can be written without having to repeat the "start" message or address byte with the slave address. 7/55 Typical application schematic TS4956 In order to read data from the TS4956, after the "start" message, the MCU must send and receive the following data: ● send byte with the I²C 7-bit slave address and with the R/W bit set high. ● receive the data (control register value). All bytes are read with the MSB bit first. The transfer of read data is ended with a "stop" message. When transmitting several bits of data, the data can be read with having to repeat the "start" message and the byte with slave address. In this case the value of the control register is read repeatedly. Figure 3.

The output amplifiers can be configured in 7 different modes as one SE (single-ended) capacitively-coupled output, two phantom ground headphone outputs and two BTL outputs. Figure 1 on page 5 and Figure 2 on page 6 show these configuration schemes and Table 7 on page 8 describes these configurations in different modes. This chapter gives information on how to configure the TS4956 in an application. 4.1 Output configurations 4.1.1 Shutdown ) s ( ct u d o When the device is in shutdown mode, all of the device’s outputs are in a high impedance state. r P e t e l o 4.1.2 Single-ended output configuration (modes 5 and 6) When the device is woken-up via the I²C interface, output amplifier on output MLO is biased to the VCC/2 voltage. In this configuration an output capacitor, Cout, on the single-ended output is needed to block the VCC/2 voltage and couples the audio signal to the load. ) (s s b O VCC/2 voltage is present on this output in all modes (modes 1 to 7) to keep the output capacitor Cout charged and to improve pop performance on this output during the switching between any given mode to mode 5 or 6. t c u When the device is in mode 5 or 6 where the single-ended output MLO is active, all other outputs are in a high impedance state. d o r 4.1.3 Phantom ground output configuration (modes 3 and 4) P e In a phantom ground output configuration (modes 3 and 4) the internal buffer is connected to the PHG pin and biased to the VCC/2 voltage. Output amplifiers (pins LHP and RHP) are also biased to the VCC/2 voltage. One end of the load is connected to output amplifier and one to the PHG buffer. Therefore, no output capacitors are needed. The advantage of the PHG output configuration is that there are fewer external components compared to an SE configuration. However, note that in this configuration, the device has a higher power dissipation (see Section 4.3: Power dissipation and efficiency on page 40). s b O t e l o All other inactive outputs are in the high impedance state except for the MLO output, which is biased to VCC/2 voltage. To achieve better crosstalk results in this case, each speaker should be connected with a separate PHG wire (two speakers connected with four wires) as shown in Figure 1 on page 5 (instead of using only one common PHG wire for both speakers, that is, two speakers connected with three wires). 38/55 TS4956 4.1.4 Application information BTL output configuration (modes 1, 2, 7) In a BTL (bridge tied load) output configuration (modes 1, 2 and 4), active outputs are biased to the VCC/2 voltage. All other inactive outputs are in the high impedance state except for the MLO output, which is biased to VCC/2 voltage. BTL means that each end of the load is connected to two single-ended output amplifiers. Therefore we have: single-ended output 1 = Vout1 = Vout (V) single-ended output 2 = Vout2 = -Vout (V) and Vout1 - Vout2 = 2Vout (V) ) s ( ct For the same power supply voltage, the output voltage amplitude is twice as high as the output voltage in the single-ended or phantom ground configurations and the output power is four times higher than the output power in the single-ended or phantom ground configurations. u d o r P e 4.2 Power limitation in the phantom ground configuration t e l o A power limitation is imposed on the headphones in mode 3 and 4. Limitation of output power is achieved by limiting the output voltage and output current on each amplifier. s b O The maximum value of the output voltage, Vout max, is set to a value of 1.65 V in order to reach a maximum output power of the sinusoidal signal of around 40 mW per channel with a 32 Ω load resistance and THD+N
