DAC (LSI5: UPD63200GS)
UPD63200GS is a two-channel 16-bit Digital to Analog Convertor consisting of resistor string, output
amplifier and zero offset circuit.
The DAC receives 16-bit serial data output from the DSP. The data contains digital sound data of the
melody, chord, bass, and percussion for the right and left channels. The DAC converts the data into analog
waveforms by each channel and output them separately.
