TAS2563RPPR explains

TAS2563RPPR is a course is optimized, can be worth the height power efficient drive inputs amplifier of D class frequency to the number of small-sized loudhailer. This D kind amplifier can use compositive type 11.5V H below the batteries voltage of 3.6V kind step up function provides power of 6.1W peak value 4 Ω load, or exterior 12V power source is used to provide power of 10W peak value 4 Ω load below mode of step up bypass.

Piece on apparatus of state of heart of support of low defer DSP (the SmartAmp loudhailer of TI) protects algorithm. Compositive electric current and voltage detect the function can undertake to loudhailer real time is monitored, changing course of peak sound pressure thereby (SPL) while maintain loudhailer to not be damaged bad.

Function of compositive step up of lead H class can be in during broadcasting, trends adjusts step up voltage, the efficiency that improves batteries power supply system thereby prolongs battery life. To power supply of type of stabilized voltage wall system, TAS2563 still has pattern of step up bypass, the power source voltage that support is as high as 16V in order to achieve higher output power.

Input of two PDM microphone simplified the frequency signal catenary of two-way frequency system, can rise digital microphone and join of lead plane processor. Batteries dogs limiter of peak value voltage is had owe control protective function, can optimize amplifier to be in whole charge the surplus in cycle, prevent a system to close thereby.
