Part Number: THS4304-SP

Hi team, working with a customer on this device. Some questions on the implementation of the device:

Datasheet on page 12 under General applications, discusses that 0.1uF ceramic cap is critical for power supply bypass. Text implies maybe more than one is needed, if so how many?
Are you recommending a Ferrite bead between the supply and +Vs? If so, what value?
Why do you have Resistor “C5” in the picture below? Is this a Resistor, or a Cap? Figure 44, under Non-Inverting Single Supply Operation section, page 18.

Thanks in advance.

Hi Kannan,

have you seen figure 37 of datasheet and the bill of materials on the following page?

C5 refers to figure 37. Figure 44 means that instead of C5 from figure 37 a 0R resistor shall be mounted. The same is valid for C7, C8 and C9.

Thanks Kai. I missed the BOM table in my printout!
