The PT2834 is a system integrated audio chip with audio processor, stereo/mono Class-D amplifier, 16Bit audio DAC and Class-AB headphone driver. The signal path is pure analog processing to maintain high performances and low power consumption. The input selector accepts multiple analog sources and digital audio source can be converts to analog by built-in 16bit audio DAC. The PT2834 also provides auto level control prevent the line out and class-D amplifier output clipping and distortion. The functions control is through the I2C registers.
