Power Limitations: While it can drive most IEMs and efficient headphones (around 65mW at 32 Ohms), it may struggle with high-impedance "power-hungry" over-ear headphones [6, 10].
In the open-source community, getting the most out of this chip sometimes requires custom device tree overlays or specific kernel modules to unlock features like high-gain microphone modes or specific DSP profiles.
Integrated Controls: The chip supports in-line controls (volume/play/pause) and microphone input for calls.
A minimal working circuit includes:
Technically, the chip is designed for transparency. Its low output impedance (< 1 ohm) ensures that it doesn't color the sound of multi-driver IEMs (In-Ear Monitors), maintaining a flat frequency response across the spectrum. 5. Design Considerations for Engineers
