TAS5727: Total Harmonic Distortion + Noise vs Frequency for 4-Ω Load

Henry Wang

Part Number: TAS5727

Dear Sirs,

My customer would like to know the test result about Total Harmonic Distortion + Noise vs Frequency for 4-Ω Load at Vin-12V.(datasheet only provide 8-Ω Load data) Do you have data can be share to us?

Another question about I2C application as below.

Please help to review function block as below, when we changed I2C path to another TAS5727, (example: from FR/FL to Rear R/L).

Do you think there have or not any design risk for I2C?

    Henry,

    We will need time to collect the data.

    For the I2C routing, I do not see any issue as long as you configure the TAS5727 to be a different address for each device on the same I2C line. One device should be 0x54 and the other 0x56, this is controlled by pull up or down on A_SEL_FAULT pin at start up. Please see datasheet section 10.3.2.1.

    Regards,
