PVDD Supply (continued)

A separate power supply is required to drive the gates of the MOSFETs used in the output stage of the speaker

amplifier. This power supply is derived from the PVDD supply via an integrated linear regulator. A GVDD pin is

provided for the attachment of decoupling capacitor for the gate drive voltage regulator. It is important to note

that the linear regulator integrated in the device has only been designed to support the current requirements of

the internal circuitry, and should not be used to power any additional external circuitry. Additional loading on this

pin could cause the voltage to sag, negatively affecting the performance and operation of the device.

Another separate power supply is derived from the PVDD supply via an integrated linear regulator is AVDD.

AVDD pin is provided for the attachment of decoupling capacitor for the TAS5805M internal circuitry. It is

important to note that the linear regulator integrated in the device has only been designed to support the current

requirements of the internal circuitry, and should not be used to power any additional external circuitry. Additional

loading on this pin could cause the voltage to sag, negatively affecting the performance and operation of the

device.
