SLOS989B November 2017 – November 2019 TAS5720A-Q1
PRODUCTION DATA.
To place the TAS5720A-Q1 into Hardware Control Mode, the HW/SCL pin should be pulled HIGH (that is, connected to the DVDD supply through a pull-up resistor). If the device is to operate in Software mode instead, the HW/SCL pin should be connected to the system micro controller I2C SCL pin or similar. When operated in Hardware Control mode, the output pins should be connected as shown in the Typical Application Circuit Diagrams.
In Hardware Control mode, the amplifier selects its source signal from the right channel of the stereo signal presented on the SDIN line of the Serial Audio Port. To select the left channel of the stereo signal, the LRCK can be inverted in the processor that is sending the serial audio data to the TAS5720A-Q1.
