Isolator HAT has been designed to isolate between an SBC and DAC, and it works on both master and slave DAC’s. By isolating your SBC board from the DAC board, using separate GND and Power supply lines, all possible noise and jitter coming from the source can be stopped and completely isolated prior to the DAC board!
The Isolator will work on I2S Master Mode and Slave Mode by switch(SW5) selection on board. Thw i2c & GPIO's are also isolated.
Full galvanic isolator between SBC/DAC
Works on both master and slave DACs
Switch selection for Master/Slave.
Switch selection for SPI isolation.
Isolated the I2C ,SPI ,I2S and GPIO’s
We recommend using LIFEPO4 batteries, and the Isolator will in turn provide 5v/06A using LT3042 and 3.3V using LT3042 LDOs.
Sampling Frequency ranges from 8 kHz to 384 kHz.
Ultra-low-noise voltage regulators & LPF for optimal audio performance.
