ADA4350: On-Resistance

Hello,

 

I will connect the SWA_OUT pin of ADA4350 with an outside inverting amplifier circuit.

I do not use the ADC DRIVER of ADA4350.

 

The ADA4350 has the switch, and the on-resistance is hundreds of ohms.

I think that the on-resistance is too large to connect SWA_OUT pin directly with the inverting amplification circuit.

Should I include the buffer between SWA_OUT pin and the inverting amplification circuit?

 

Best Regards,

Mr.K
