Description

 

The XPT9911 is an FM-free, class AB / D optional (D Class anti-break Sound) Power Amplifier.Maximum output power up to 12W( 2Ω, BTL load, THD<10%), total harmonic loss in the audio range True noise is less than 1%.The application circuit of the XPT9911 is simple and requires only a pole A few peripheral devices with integrated feedback resistors;no external coupling is required for the output Capacitors or Bootstrap capacitors and buffer networks. The XPT9911 is available in an ESOP16 package and is particularly suitable for large tones Amount,small weight portable system.Xpt9911 internal with overheating self Dynamic shutdown protection mechanism; stable operation,gain bandwidth product up to 2.5 MHz, And unity gain stability.Feedback resistor built-in, by configuring the periphery Parameters can adjust the voltage gain of the amplifier and the best sound quality effect, square It will be applied.Is a video megaphone, HiFi megaphone and other 2 lithium batteries should With a perfect audio solution.
