Features 1.Connection: Except for VCC GND, which is connected to power supply, the remaining GND LRCK DATA BCK is connected to I2S signal input. 2.PLL Upfrequency: The internal PLL upfrequency of DAC decoder board is only used to generate internal MCLK clock, which cannot raise the sound sampling rate. 3.I2S Input: DAC decoder module supports direct input of I2S format left justified signal (need to switch manually). 4.Two Filter Modes: This DAC module supports two filter modes, normal mode or low latency mode (set in the board FLT port). 5.With 3.5mm Port: DAC decoder assembled board adds a headphone output interface, which can be directly connected to 3.5mm interface headphones. 6.Premium Sound: Direct output 2.1V RMS sound voltage, high frequency without burr, low frequency full, better dive, beyond ES9023. specificationItem Type: DAC Decoder Board_x000D_ Material: PCB_x000D_ Power Supply Voltage: DC 5V-10V_x000D_ Maximum Support: 32bit Data 384K Sampling Rate_x000D_ SNR: 112db, Distortion -93db PackageList1 x_x000D_ _x000D_ DACDecoderBoard Note1. The power supply should not be connected to the reverse, the reverse will damage the board, the voltage exceeds 10V will also damage the board._x000D_ 2. This board does not need to connect to MCLK chip, internal PLL upfrequency generates MCLK clock, which is much better than using asynchronous clock.
