https://devzone.nordicsemi.com/f/nordic-q-a/43196/some-technical-audio-spec-of-thingy52Hi team, One of my customer wants to evaluate the design of Thingy52, using PWM output &amp; H bridge to power the speaker. But as for audio related issue, they are asking if Nordic has SNR/ Frequency response and distortion factor of the design?
