Crop of the audio DAC and pre-amplifier: U17, a uPD6376 16-bit stereo DAC (LOUT pin 11, ROUT pin 6, with C73 47 uF 10 V on the reference pins and C102 0.1 uF on the supply), feeding two LM324 sections, U100D (right, output pin 14) and U100C (left, output pin 8), through 22 k resistor and capacitor filters (R99, R101, R102, C74, C75, C76; R103, R104, R105, C77, C78, C79). U100D is drawn on the VS supply with C80 0.1 uF; R106 and R107 (5.1 k) load the outputs. From Jonathon W. Donaldson's community redraw of the NTSC Super NES main board (SNS-CPU-GPM-01/02 and SNS-CPU-RGB-01/02), revision 1.5, 24 February 2014. Not a Nintendo document.
