Dear sir,

now we are looking for an TAS5424A 4 channel amplifier, how do we interface with rasberi-pi model, in I2C commounication.

The TAS5424A uses a standard I2C interface. You will need supply a pull up resistor to a 3.3Vdc or 5Vdc supply from each of the I2C pins. Your Raspberry Pi will need to have a SCL(clock) output pin and a SDA (data) bi-directional pin to communicate with the TAS5424A. Make sure you have the ground pin of the Raspberry Pi referenced to the ground pin of the TAS5424A.

The TAS5424A is not recommended for new design, so please use the TAS5424C-Q1 for new designs.

I cannot help you with the details of the Raspberry Pi.

But, in datasheet they doesn't provide the application diagram for TAS5424C-Q1, how we can get that design information.

Thanks & regards

Kiran,

The I2C circuits are no different in the TAS5424C-Q1 when compared to the TAS5414C-Q1. The application schematic in the datasheet is valid for both devices for the I2C section.
