1-CH H.Q. Speech Controller

5.11Push-Pull DAC & Current DA Output

SNC21300A is an advanced chip to be designed having two optimal methods to

play out the voices. One is DAC and the other is Push-Pull DAC. Upon user’s

applications, user can select either DAC or Push-Pull DAC in his design. Please be

aware that only one method can be activated at the time.

Push-Pull DAC: An 8-level volume control Push-Pull DAC circuit is built-in

SNC21300A. The maximum resolution of Push-Pull DAC is 12 bits. Two huge

output stage circuits are designed in SNC21300A. With this advanced circuit, the

chip is capable of driving speaker directly without external transistors.
