CSR8675 Wireless Adapter Bluetooth 5.0 Receiver Board ES9018 I2S DAC SQ875 Audio Decoder 24Bit/96Khz LDAC with Antenna | Электроника

SQ875 Bluetooth audio receiver adopts CSR8675 Chip solution Bluetooth digital audio signal reception, ies digital signal transmission to ESS9018 decoding chip, analog audio signal output through dual op amp gain filter output.
The SQ875 supports Bluetooth wireless reception and one AUX analog audio input for switching output. Lossless switching with relays will not affect sound quality.
By default, the module enters AUX line mode, the switching mode is automatic switching, and preferably Bluetooth.
The SQ875 module is a high-level version that supports the LDAC protocol and supports a sampling frequency of 24 bits / 96 kHz, which exceeds the sampling frequency of 24 bits / 48knz APTX-HD.
SQ875 is a DC single-supply switching power supply, a wide range of DC voltage 5 V-32 V DC, multi-stage voltage regulator product design, Bluetooth module, DAC chip, operational amplifier chip are powered by independent power management chip, op amp uses dual (positive and negative) 13 V power supply, fever level design.
