Hello team,

My customer have below questions regarding C1~C4 in typical application, can you support please?

Vcc=5V, is it okay to use 3V to 5.5V table? They want to use 0.47uF for C2~C4 especially.
Should they consider capacitor DC bias characterisitcs?
They select 15V torelance for C1~C4, is it enough torelance?

Regards,

Hi Youhei,

1. Yes, they can use the 3V to 5.5V range for 5V VCC operation.

2. No, this is not necessary. However, the customer needs to use the exact capacitors values in that table for C1 - C4. Any deviation from that table means the device will not operate properly, and we will not support any other issues.

3. Yes, 15V is the correct rating.

Best,

Ethan
