Analog Positive supply voltage
MS6337
16-Bit Stereo Audio DAC & Mono 1.8W Power Amplifier
Plus Stereo Headphone Function
Description
CAP discharge. This pin is functional only as the system is shutdown.
Headphone input detection.(refer to Page.14 for detection levels)
A logical low sets BTL mode, a logical high sets SE mode.
Capacitor connected
Right channel input
Negative supply voltage for right channel of power amplifier
SE right channel output
Positive supply voltage for right channel of power amplifier
Positive output of BTL
Positive supply voltage for left channel of power amplifier
SE left channel output or negative output of BTL
Negative supply voltage
Negative supply voltage for left channel of power amplifier
Left channel input
The shutdown mode selects the shutdown logic level of the SD pin.
SD_MODE = 0, the device is shutdown when SD is logic low.
SD_MODE = 1, the device is shutdown when SD is logic high.
Negative supply voltage
Digital Ground
DAC shutdown pin. /DAC_SD=0, DAC is shutdown. /DAC_SD=1, DAC is Active.
Audio data input
Audio word select input
Audio bit clock input
