HI team,
1. Could you please help me double check my design which can switch gains of 200V/V and 400V/V via TLV376?
2. Could you please provide a reference design with a switch which can switch gains of 200V/V and 400V/V via TLV376?
Best regards
Zhihong Huang
Hi Wesley,
The BW of your circuit is approx. 16kHz to 33kHz from Gain=400 to 200 respectively. Please see the attached simulation.

You also would need to insert the switch capacitances into this sim and, for single supply, Vin =0V will be out of range on the low side (check output swing)
HI Raymond,
Thanks for your reply,
1. Could you please recommend a switch capacitance for my design?
2. Could you please share the document about how to select the switch capacitance in such design?
Best regards

Hi Wesley,
would you be so kind and answer my question? :-)
"What is your signal frequency range?"

HI Kai,
I am so sorry that i miss your reply.
It is below 10khz.
