YMU759
DAC
Converts digital signal from FM and ADPCM section to analog voice signal with resolution of 16 bits.
Headphone output
This section supports stereophonic analog output for the headphone. Monaural output is available by changing
the setting. And built in volume adjust output level.
EQ amplifier
This section is used to set the response of filter or the gain by externally connecting a resistor and capacitor.
Speaker amplifier
A speaker amplifier is built in this device, which maximum output is 550 mW at AVDD=3.6 V.
Built in volume adjust output level in front of amplifier.
Low ripple is provided.
Clock generate
This block makes a necessary clock by increasing 2 to 20 MHz clock inputted through CLK1 terminal using the
built-in PLL.
The clock generated in this section is supplied to the inside of digital circuit.
