Hi Team,
The customer is using PCM1753. In his design, he tests the SNR value and it is only 72dB. He does a test. He removes the LEFT_LPF and RIGHT_LPF circuit ,and connects two 10uF capacitance to 7 pin and 8 pin. That is the output for 7 pin and 8 pin is directly to the headphone. Finally, he can hear music from the headphone , but there is a lot of noise. Look the attachment.
What is the reason? Is the schematic correct? How to solve the issue?
Thanks,
Best Regards,
