RM1307731646913779

SQ875 Bluetooth audio receiver board adopts CSR8675 chip solution Bluetooth digital audio signal reception, I2S digital signal transmission to ESS9018 chip decoding, output analog audio signal through dual op amp filter amplification output. The SQ875 supports wireless Bluetooth reception and one AUX analog audio input for switching output. Lossless switching with relays will not have any effect on sound quality. The module defaults to AUX line mode, the switching mode is automatic switching, and Bluetooth is preferred. The SQ875 module is a high-level version that supports the LDAC protocol and supports a sampling rate of 24bit/96khz, which exceeds the -HD's 24-bit/48knz sampling rate.

SQ875 is a DC single-supply power supply, wide voltage range DC 5V-32V, product design multi-stage voltage regulator, Bluetooth module, DAC chip, op amp chip are powered by independent power management chip, the op amp uses dual (positive and negative) 13V power supply, Fever level design
