SNC21268A
1-CH H.Q. Speech Controller
5.11Push-Pull DAC & Current DA Output
SNC21268A 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
SNC21268A. The maximum resolution of Push-Pull DAC is 12 bits. Two huge
output stage circuits are designed in SNC212680A. With this advanced circuit, the
chip is capable of driving speaker directly without external transistors.
