PCM5100, PCM5101, PCM5102 are TI company's audio stereo DAC with maximum output voltage of 2.1VRMS, supporting 32-bit, 384kHz PCM interface. This chip has market-leading low out-of-band noise, selectable digital filter latency and no DC blocking capacitors required.
The PCM510x family provides a monolithic CMOS stereo digital‑to‑analog converter with selectable digital‑filter latency, integrated PLL and pop‑free operation. It delivers 2.1 V rms ground‑centered outputs, eliminating the need for external DC‑blocking capacitors, and supports 16‑ to 32‑bit audio data at sample rates from 8 kHz to 384 kHz.
The devices operate from a single 3.3 V supply for analog, digital and charge‑pump rails, feature an intelligent mute system, and can drive loads as low as 1 kΩ. Detailed electrical, mechanical and terminal specifications are provided for designers.

The DACs provide a 2.1 V rms ground‑centered analog output.
All three supply rails (AVDD, CPVDD, DVDD) operate from a 3.3 V nominal supply, with a permissible range of 0.3 V to 3.9 V.
The devices support sampling rates up to 384 kHz.
The PCM5102 achieves a dynamic range of 112 dB.
