In its Original packaging

The PCM69AU converter is a digital-to-analogue (DAC) audio converter integrated into the Yamaha O2R digital console (used in the analogue output, monitoring and DAC sections).

Function: Dual 18-bit CMOS digital-to-analogue audio converter (stereo DAC).

Architecture: Advanced Segment DAC (combines Sigma-Delta modulation for lower-order bits and traditional DAC architecture for higher-order bits, reducing zero-crossing distortion).

Resolution: 18 bits per channel (2 independent channels on a single chip).

Dynamic Range: ~110 dB (typical).

THD+N (Total Harmonic Distortion + Noise): -96 dB (typical at 0 dB output).

Signal-to-Noise Ratio (S/N): 110 dB.

Sampling Frequency (Fs): Up to 96 kHz (supports standard 44.1 kHz / 48 kHz).

Supply Voltage: VDD = +5V (analogue and digital).
