DAC Headphone Amplifier DAC01 MAX97220 STM32 24bit 96kHz

FX-Audio offers with the DAC-X4 a digital/analog converter with headphone amplifier, at a very affordable price. This one embeds a DAC01 conversion chip, allowing it to support PCM sampling rates up to 24bit 192kHz. This one is associated with a MAX97220 headphone amplifier chip, offering a power of 2x150mW under 32Ω.
As for the connections, the DAC-X4 remains classic and efficient, with USB-B, Optical Toslink and Coaxial as inputs. For the outputs, we simply find stereo RCA and 3.5mm jack for the headphone output.
