Stereo 2W Class-D Amplifier With Built-In Audio Processor
The PT2334 is an integrated stereo 2W Class-D amplifier accompany with a Class-AB headphone driver. The input interface accepts both analog and digital audio sources; the chip included a 16-bit DAC to convert digital audio source to analog signal. The signal process is basically in analog domain to maintain the high performances and low power consumption. The PT2334 also provide very useful multi-sources selection (Up to 4 sources) and tone control functions, thanks for the advanced CMOS technology now we could combine both audio processing and amplification into a single chip. The whole chip functions are controlled via I2C bus.
