TAS2770: TAS2770 THM data

Part Number: TAS2770

dears, i want to know TAS 2770+ 2W, 4ohm SPK*2, when play bass/alto/soprano music, how about the package temprature?

is there any THM data for this AMP?

  • Hi Yufeng,

    Welcome to e2e.
    All available information is included in the data sheet.

    You can estimate the power dissipation of the device from the efficiency provided in the data sheet. Efficiency plot provides efficiency and output power, thus supply power can be obtained.
    The power dissipation will be the difference between supply power and output power. The temperature of the device is based on power dissipation, and it also depends on the heat dissipation capabilities of the board design. A good layout design will provide good heat dissipation through the GND plane so that the device does not overheat.

    It is recommended to follow the layout guidelines provided in the data sheet and also try to replicate the design from the EVMs.
