Part Number: PCM1804 Other Parts Discussed in Thread: PCM1822 , TAA5242
I'm looking to use the PCM1804 for a balanced line level (XLR) input. Ideally without a negative voltage supply. Should I use an op-amp to add the DC offset from Vcom or can I just…
Hi Danny,
In all the PCM devices listed in the table (except for PCM1822), the supported max. swing is 2Vrms for differential input (and in the case of the TLV320 devices, 1Vrms single-ended input).
The PCM1822 operation supports up to 1Vrms full-scale…

You see this in the datasheet of the PCM1822. Its a few pages into the datasheet.
The setup for single ended inputs is correct
Part Number: PCM1821 Other Parts Discussed in Thread: PCM1822-Q1 , PCM1820 , PCM1820-Q1 If only one channel of the PCM1821 analog input pair is needed, what is the recommended connection for the other pair?
Does this same recommendation apply to PCM1820…
Part Number: PCM1821 Other Parts Discussed in Thread: PCM1822-Q1 We need to make sure our PCM1821 (or PCM1822-Q1) board is as quiet as possible, but the system we're connecting to is fairly noisy. Thus we want to isolate our analog signals, power…

Hello Ravindra,
Thank you for reaching out. As you have noticed, the PCM1821 does not support the Dynamic Range Enhancer (DRE). The DRE monitors the incoming signal amplitude and accordingly adjusts the internal DRE amplifier gain automatically (see sections…
