Hi Tetsuji,

You might consider a device like ADS127L01 if you also need good THD+N performance. If this does not fit, are there any other restrictions on the interface or any other requirements that would help us narrow down the options?

Best,

Zak

Hi Zak

thank you for answering.

I'm looking for a replacement for Asahi Kasei AK5572. The PCM1840 has a sample rate of 7.35KHZ to 192KHZ, so I think it meets the requirements except for 5.12khz and 6.5536khz. Can it be used?

Best Regards,

Hi Tetsuji,

PCM1840 is part of the same family as the TLV320ADCx140 and will not support these non-audio sample rates. I think it may be possible with the PCM4204 or PCM1864.

Best,

Zak

Hi　Zak

Thank you for your reply.
I understand that the pcm1840 is not suitable for this application.
Consider whether you can use pcm4204 or pcm1864.
