NY7A
NY7B / NY7C
device as PWM output or DAC output.
2. For NY6 series, the Voice Output only set the initial mode, user can change this setting
by using AudioMode command
Ex.
Voice Output
= PWM+DAC
PWM Current:
Pulse Width Modulation output current. NY6 series supports Normal /Ultra.
Ex.
PWM Current
= Ultra
RampUp/Down:
User can turn off RampUp / RampDown function under DAC mode.
Ex.
RampUp/Down
= Disable
Note: Not all applications need to disable RampUp/RampDown feature, because it can
prevent “pop” sound caused by RampUp/RampDown movements with external OP
Amp output.
NY7
Voice Output:
Set the driver type of the speaker. The PWM option
means PWM output can be connected with speakers directly. The
DAC voice output needs to be connected with transistor and bias
resistor. Push-Pull is push-pull output. NY7A series provides the PWM
/ DAC / PWM+DAC option (default = PWM+DAC). NY7B / NY7C
series provides the DAC and Push-Pull option. Only one output is
available in the same time (default =Push-Pull).
Note:
1. The PWM+DAC feature is for automatically detecting
external device as PWM output or DAC output.
2. For NY7 series, the Voice Output only set the initial mode, user can change this setting
by using AudioMode command.
Ex.
Voice Output
= PWM+DAC
Ex.
Voice Output
= Push-Pull
PWM Current:
Pulse Width Modulation output current. NY7A series
supports Normal / Ultra.
Ex.
PWM Current
= Ultra
Note: NY7B / NY7C series do not support the PWM Current
setting.
RampUp/Down:
User can turn off RampUp / RampDown function
under DAC mode.
