Hi, guys. I'm trying to work with Opus applications using PCA10056 v1.0. In order to play Opus fils using the nRF52840,
do I need audio DAC + audio amplifier to create sound on a 3.5mm headphone jack or 1W 8 Ohm speakers?
For instance, adding TI's TLV320DAC3101 (32-bit Low-Power Stereo Audio DAC With Stereo Class-D Speaker Amplifier) is mandatory for playing Opus files?
Or using nRF52840's PDM (Pulse density modulation interface) / PCM will do the job so that I only need the audio amplifier?
