SNC749
16-bit Voice Processor
9. Push-Pull DAC
To play out voices, SNC749 only contains Push-Pull DAC (direct drive) for user to
output voice.
10. Regulator
The SNC749 provide a linear regulator for core power (CVDD). The accuracy output
voltage is 2.8V±0.2V and it can be power-downed by software.
Features:
Input supply voltage: 3.6V ~ 5.1V
Dropout voltage of 0.8V at 20mA output current:
Output current: 20mA
Power down current: <1uA
Accuracy output voltage: 2.6~2.8V
