There is a list of coefficiants , By writing to these coefficiants we can get a mix of signals that are routed to each DOUT
Your schematic connection where the 2 devices are slaves is OK
Part Number: PCM1865
Been digging through these forums for a few weeks now as I attempt to debug my PCM1865 ADC with a Raspberry Pi Compute Module 4. Here is my current .dts file

Part Number: PCM1865 Other Parts Discussed in Thread: PCM1864 , PCM1863 , PCM1862 We are currently on a project in which we are using the TI PCM1865DBT audio codec. For audio input we are using a digital microphones (MEMS) which are connected to the DMIN…
Part Number: PCM1865 Hi, I have connected PCM1865's Vref to my OPA1865's VCOM, im wondering if i should divide it by two or not. My OPA is conected to +18v / -18v. But Ive read VCOM should be connected to AVDD/2 so im not sure. Should i divide…
Part Number: PCM1865 Im connecting OPA1637DGK differential outputs to a PCM1865, Im having toruble understanding the common-mode voltage connection. Do I need it? When do I need it? I thought i did so i connected them as shown in the pitcture, but im not…

Hello IT team!
I'm working on a project where I need to multiplex the following X2 connections (so we can focus on only 4 of the 8 PCM1865…
Part Number: PCM1865 Hello, expert. Would you tell me the correct settings for DPGA? On the datasheet(Rev.D 2018-Mar), [Table 48] Shows the data bits. Gain can be varied with 0.0dB to 7.5dB.
But, [Figure 28] Shows: Gain can be varied with 0.5dB to 11.5dB…
Part Number: PCM1865 Hello, experts. I was confused by the description on the datasheet(Rev.D 2018-Mar) regarding with the interrupt function. I want to use the controlsense function in active mode, and interrupt function.
On page.57: >The pulse width of…
Part Number: PCM1865 Other Parts Discussed in Thread: OPA1637 , I have a PCM1865 with a differential input from a OPA1637, I've heard that if the Vref (from PCM) is connected to the VCOM (of the OPA) I can remove the 10uF capacitors on the input reducing…
