XA9901
XA9901 is a non FM interference, AB/D class optional power amplifier (D class with anti distortion function). At a working voltage of 8.4V, the maximum driving power is 10W (4 Ω, BTL load, THD<10%）， The total harmonic distortion noise within the audio range is less than 1%. The application circuit of XA9901 is simple, requiring only a few peripheral devices and integrating feedback resistors; The output does not require external coupling capacitors, pull-up capacitors, or buffer networks.
XA9901 is packaged in ESOP8, making it particularly suitable for portable systems with high volume and low weight.
