Part Number: PCM1754

Dear Specialists,

My customer is considering PCM1754 and has a question.

I would be grateful if you could advise.

---

I'd like to use FMT fixed at low.
Could you please let me know the maximum value of external resistance?

I appreciate your great help in advance.

Best regards,

Shinichi

Hi Inoue-san,

If the customer would like FMT to always be low, then external resistance does not matter. They can simply tie the pin to GND.

Best regards,

Hi Jeff,

Thank you for your reply.

I understand.

When FMT is low, it can tie to GND.

I'll share the customer.

I appreciate your great help and cooperation.

Best regards,

Shinichi
