Hi Ryu,
No, I just happened that I had a similar behavior ( The lower current at the output along with increased VCOM voltage ) that was due to the VCOM cap.
I don't have any supporting proof that the type is very critical but at least we know it is the…
Hello , looking at datasheet of NE5534 , its min supply range is +/-3V , so 9V power supply should be fine for the NE5534, in fact we use this IC for many of our DACs, I am not familiar with the LT chips so I can not comment.
For specific questions regarding NE5534…

Part Number: PCM1794A Other Parts Discussed in Thread: PCM1792 Hello,
When are the I2S data clocked into the DAC in the PCM1792/1794 when used in mono mode? Should one channel be delayed relative to the other or will both DACs receive data on the same…
Part Number: PCM1794A Other Parts Discussed in Thread: NE5534 , , PCM5121 Hello,
One customer used PCM1794A for his design, the output IV and LPF used NE5534, its power supply is +-12V. If the input sample rate is 48K, 16bit, and I2S 18Khz signal, the…

Part Number: PCM1794A Hi Team,
Good day. I am posting this inquiry on behalf of the customer.
At present, we use the DAC PCM1794A to make a batch of development board, debugging found that C168 and C203 two capacitors use the recommended capacity of 2700PF…
Part Number: PCM1794A Other Parts Discussed in Thread: PCM1794 , OPA2132 , NE5534 Hello!
I want to build a PCM1794 DAC and use a 12V battery with it. Please see if I organized one polar supply for LPF correctly?
Also LT1028 is currently out of stock. …
