Part Number: PCM3008
Other Parts Discussed in Thread: PCM3002

Tool/software:

Hello team,

My customer is having noise problem on PCM3008.

Details on the thread below.
https://e2e.ti.com/support/audio-group/audio-internal/f/audio---internal-forum/1342711/pcm3008-noise-from-vout-even-when-there-is-no-input-signal?tisearch=e2e-sitesearch&keymatch=PCM3008%20kuwahara#

They are thinking of using alternative device.
Which device do you recommend?

I am thinking PCM3002 is a rgood candidate, could you highlight some differences between PCM3008 and PCM3002?

Best Regards,
Kei Kuwahara

    Hi Kuwahara-san,

    The PCM3002 is an upgrade over the PCM3008 in many areas: THD+N, SNR, DNR, bit resolution, and consumes less current from the supply. They are not pin to pin compatible however and will take a bit of rework in order to design the device in place of the PCM3008, but you will get better performance across the board.

    Best regards,
    Jeff McPherson
