Part Number: PCM1789-Q1 Other Parts Discussed in Thread: PCM1789 , PCM5102-Q1 We would like to use #PCM1789 as replacement for Analog Devices part # AD1859 ? Is this a good option? Or any other good suggestions to replace with?
Hi AGXIN,
The PCM1789 minimum impedance for an DC coupled path to ground is 15kohm.
I am not quite sure about the impedance for the MIC, though I think it would really be dependent on the MIC rather than the ADC.
Thanks!

Part Number: PCM1789 Hello,
The PCM1789 spec lists bipolar zero error at ±1% of FS typical. Any additional data available regarding drift over time or temp? Wondering how realistic it is to calibrate that out and have good repeatability on driving to…
Hi, Bernat,
Welcome to E2E, Thanks for your interest in our products!.
The Evaluation board for the PCM1789 was discontinued because the board design was very old and there was no update for it. There are no plans to obsolete the PCM1789, so you should…
Part Number: PCM1789 hi,
we are designing w/ PCM1789 and we are wondering about the effects of noise on the AVCC rail on the DAC's performance...
do we have any characterization data? any filter recommandation or a part to generate the supply for…
Hi Deepak,
The schematic looks good.
We also recommend a LPF on the outputs of the PCM1789 with an fC of ~.5fS. Ideally this would be a 2nd order active filter, but a RC may be acceptable in the application as well.
Thanks!

Part Number: PCM1789-Q1 Hi Team,
We are using DAC PCM1789-Q1 in one of our design.
We are operating the DAC in I2C Mode , While testing we observed that when try to Detect device on U-Boot ,it does not Reply (NACK on I2C).
But On Kernal same I2C…
Part Number: PCM1789
somehow it looks like the PCM1789 generates noisy background noise with some frequency loss or drift. the volume is also very high. i observed the signal right coming out of PCM1789. I am using hardware control with I2S audio(tried…
Part Number: PCM1789-Q1 Tool/software: Linux We planned to integrate Codec Chipset PCM1789-Q1 in our design. but we are unable to find the Linux driver support for this chip.
Kindly help us in getting this driver. We are using Kernel version 4.4.36
