Since the use of high fidelity headphones is a growing trend for portable audio playback, higher performance DAC and Headphone Amplifiers are demanded. This system converts digital audio from USB, SPDIF, or optical sources into analog using PCM5242 audio DAC. A high performance TPA6120A2 headphone amplifier in conjunction with the differential DAC achieves stunning musical clarity and definition as well as industry leading noise performance, critical for low noise headphone playback. The power supply architecture is designed to work from a 3.3V source to increase flexibility and integration into existing products and systems.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
