SC0370 - Raspberry Pi IQaudio DigiAMP+
IQaudio DigiAMP+
DigiAMP+ is a HAT compliant add-on accessory for the Raspberry Pi.
DigiAMP+ uses the Texas Instruments TAS5756M PowerDAC to deliver direct connection to PASSIVE stereo speakers at up to 2x 35wpc with variable output. Ideal for a Pi based HiFi.
DigiAMP+ can be connected to the Raspberry Pi A+/B+/RPi2/RPi3 or RPi4's 40-way pin header without any additional soldering.
DigiAMP+ must be powered from an external supply and requires a 12 to 24 DC power source to operate. DigiAMP+’s barrel connector is 5.5x2.5 mm. DigiAMP+ has been designed to provide power to the Raspberry Pi and DigiAMP+ combination in parallel, delivering 5.1 V @ 2.5 A to the Pi.
DO NOT APPLY POWER TO THE RASPBERRY PI’s OWN POWER INPUT WHEN USING DIGIAMP+.
The amplifier is by default muted at power on (mute LED lit). The mute state/LED is under software control (Raspberry Pi GPIO22).
- P5: Alternative power input for hard wired installations. POLARITY MUST BE OBSERVED!
