VOICE OUTPUT
The aPR2060 support 2 voice output mode, PWM and DAC.
The PWM mode use VOUT1 and VOUT2 pin to drive speaker directly without external components
to save cost.
The DAC mode use VOUT2 pin to output current signal. User can use the signal to drive audio
amplifier or mix with other components in their applications to provide larger voice volume.
The following fig. show circuit for different output methods: PWM, DAC, DAC with transistor, DAC
with audio amplifier AP4890B.
