The Raspberry Pi IQaudio DigiAMP+ sound card connects to a Raspberry Pi computer via its 40-pin GPIO header and is powered by the computer, so no external power supply is required. It features a Texas Instruments PCM5242 digital-to-analog audio converter with 24-bit resolution and supports sampling rates of up to 192 kHz. Audio outputs include stereo RCA and a separate headphone amplifier with a 3.5 mm jack.
