Part Number: PCM3120-Q1

I could not find the ADC resolution in the datasheet of PCM3120-Q1.

Please teach me it.

Hey,

Please expand on what you mean by "resolution". It is not very clear what feature of the ADC you are trying to understand.

Regards,

Ore.

Hi, Ore,

Thanks a lot for your reply.

The word "ADC resolution" is commonly used in the analog-digital circuit, I think.

The TI's paper explains it. https://www.ti.com/lit/an/slaa013/slaa013.pdf

Please see Page5-6.

By the way, in the PCM3120-Q1 datasheet , the specification "Output data sample word length" may be

the ADC resolution. I want to confirm it.

Best regards,

Hey,

The pcm3120 has its resolution start from 16-bit, 24-bit to 32 bit, mentioned as "word length" in the datasheet.

Think of it as the number of digital data bits at the output that represent a converted analog signal from the input. The analog signal is sampled with higher or lower resolution depending on customer's application
