XPT2068C is one class AB, take headphones drive, DC volume adjustment, has the mute function of stereo class AB bridge audio power amplifier. In the 5 v power supply conditions, THD in less than 10% of the premise, to 4 Ω external load provide 2.6 W output power, in the output signal distortion is less than 1% of the premise to the four Ω BTL load provide 1.8 W output power.

XPT2068C volume attenuation range from twenty db (DC_Vol = 0 V), to - 80 db (DC_Vol = 3.54 V), a total of 32 level control. In addition, when earphone plug access jack, audio power amplifier and the single terminal work mode driver stereo headphones. XPT2068C gather outside the control of the low power shut off mode, stereo headset amplification model, internal thermal turn off protection and short circuit protection mechanism, and using the characteristics of the circuit reduce power on and off electric appear noise (crack). XPT2068C is XPT2068 C version, have completely shut off function, with its multi-function, excellent quality, perfect price by market welcome, the user high popularity.
