PRODUCTION DATA.
The DVDD supply required from the system is used to power several portions of the device it provides power to the DVDD pin. Proper connection, routing, and decoupling techniques are highlighted in the TAS5760xx EVM User's Guide, SLOU371 (as well as the Application and Implementation section and Layout Example section) and must be followed as closely as possible for proper operation and performance. Deviation from the guidance offered in the TAS5760xx EVM User's Guide, which followed the same techniques as those shown in the Application and Implementation section, may result in reduced performance, errant functionality, or even damage to the TAS5760M device. Some portions of the device also require a separate power supply which is a lower voltage than the DVDD supply. To simplify the power supply requirements for the system, the TAS5760M device includes an integrated low-dropout (LDO) linear regulator to create this supply. This linear regulator is internally connected to the DVDD supply and its output is presented on the ANA_REG pin, providing a connection point for an external bypass capacitor. 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.
