4.3Reference 3.3. Microphone and speaker • Take an internal sound-proof measure between the microphone and speaker. Therefore, the speaker sound can be prevented from being directly transmitted to the microphone. • The distance between the microphone pickup port and the speaker sound outlet must be ≥100 mm. - Page 9 4.6Reference • The power amplifier IC output lines require differential routing, with coupled traces fully ground-guarded. Trace width should be calculated based on peak output current, and routing should be kept as short as possible. • The module’s audio output signals DACP and DACN must be routed as differential pairs and fully ground-guarded.
