Although the common Bluetooth speakers on the market are relatively cheap, their sound quality is far from satisfactory and cannot meet people's pursuit of high-quality sound. The fundamental reason is that the Bluetooth speaker box is too small and the speaker is too small, resulting in a serious lack of bass; the resonance of the plastic box causes muddy sound; the speaker is too close and the near-field sound is too narrow, etc. This design reference integrates the MaxxAudio sound enhancement chip NPCA110P, which greatly improves the problems of muddy sound, insufficient bass, and narrow near-field sound.
Supports data monitoring and PD packet injection on CC1 and CC2 lines, and voltage and current detection on VBUS and VCONN.
It can be powered via a USB port and has an LCD interface for standalone use without a PC. ERASynth Micro uses a dual-loop PLL architecture to provide fast frequency switching and fine tuning resolution. Frequency, amplitude and pulse modulation capabilities are also available.
Supports continuous or intermittent monitoring of important biometric signals such as ECG, heart rate, HRV, PPG, SpO₂, blood pressure trend and respiration. It integrates daily use and advanced research applications.
