 Hi, my name is Matteo Pavani and I'm an application engineer of ST for Digital Input Class D Power Amplifier for automotive applications. Today I want to present our power amplifier with fully digital input. Here I have a complete system fully working with four output, one power supply, one USB and one optical cable. The system is perfectly working, in fact, with a signal like this you can hear the sound. With this hardware it is possible to obtain the real value of impedance expressed as magnitude and phase and this value can be read through I2C bus. In this slide you can see a comparison between the measurement made by our device and the real impedance of the load measured through a sophisticated instrument called loudspeaker measurement and you can see this measurement on the left side of the monitor. Embedded on our power amplifier, a function called DIM digital impedance meter hallohas to recognize any kind of load or combination thereof, connect to our system and recognize exactly any misconnection with a very easy diagnosis. Here you can see the value of the load connected to our system in terms of magnitude and phase. If a misconnection of the load happen, the GUI is able to reproduce the failure that you have. This graphical user interface is available and customizable for our devices and is reporting immediately the changes of the load when some events happen and as in this case an open misconnection. As you can see in our GUI we have a different value of the load reported as open. This is very powerful and doubtfully for the system developer team. The FDA 801 is available in a very compact and thin 10x10mm LQFP64 package that enables system miniaturization. The space occupation of a fully powered system with 25V of perative voltage is as small as 3x5cm and can be further optimized as area and cost, using couple coils in same package or lower components values. All this consideration hallohas engineer to simplify the application design as to show you the total system efficiency. In this picture you see the FDA 801 efficiency. It reach values well over 90%. With these efficiency performances you can further reduce the final cost of the application because the necessary is think is really small despite the big output power of the amplifier. With FDA family you can reduce up to 30% the power dissipation compared to the other available devices thus reducing proportionally the requirement of your heat sink. With a rated battery voltage 14.4V the maximum power each channel exceed 45W allowing to fully exploit the advantages of class D, high power output and low power dissipation. The power capability of FDA family is quite high. Also thanks to the RDS on of output MOSFET is very low. Furthermore this big power comes with an enviable performance of noise and dynamic range. With a complete family of products we can achieve in a short space a different number of channels applications. Here we have a five channel solutions which measure only 4 per 5 cm and this fifth channel could be used as equal features if you use this amplifier in slug down package or fifth power channel if you use this amplifier in slug up package.
