High Fidelity Audio Headphone Playback Reference Design for Portable and Smartphone Applications
Description
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.
Features
- ±5V operation is derived from a 3.3V system power supply for integration into existing systemsGround centered outputStereo differential outputs on PCM5242 DAC for high noise rejectionNoise and Distortion performance is achieved all the way to the headphoneAutomatic sample rate switching up to 384KHzUSB interface: used for evaluation: can be omitted once designed into end equipment
