The 216k samples-per-second ceiling means it handles 96 kHz or 192 kHz audio streams with headroom — at 192 kHz the output filter corner is well above the audio band, so the reconstruction filter design is less aggressive than for a 48 kHz DAC. Four independent DAC channels let it drive a 2.1 or 4.0 audio system from a single IC — each channel has its own voltage-output stage, so the load on one channel does not crosstalk into the others through a shared output buffer.","metaTitle":"PCM4104PFBT Texas Instruments DAC, Audio, 24-bit, 216k","metaDescription":"Texas Instruments PCM4104PFBT is an active 24-bit audio DAC with 4 channels and 216k sampling rate. 48-TQFP package, ROHS3 compliant.
