#IQaudIO Pi-DAC+
|
||
|
|
||
|
The Pi-DAC+ takes the digital audio signals (I2S) from the Raspberry Pi and through the
|
||
|
onboard Texas Instruments PCM5122 DAC delivers variable output (hardware volume
|
||
|
control) analog audio to the Pi-DAC+ Phono connectors. The PI-DAC+ also, via the
|
||
|
Texas Instruments TPA6133A headphone amp, supports the direct use of headphones via
|
||
|
the Pi-DAC+ 3.5mm audio jack.
|
||
|
|
||
|
The Pi Dac uses GPIO22 to mute/unmute the Pi-AMP+.
|
||
|
|
||
|
You can use GPIO25 to connect an IR sensor and GPIO23/24 for a rotary encoder. Both of
|
||
|
these parts are optional, but are broken out on the Pi-DAC+ for convenient access.
|
||
|
|
||
|
Note: pins marked as optional can be used for general purpose if those add-ons are not enabled by software.
