I want to use analog switch(ADGxxx) to switch OP feedback resistor to create different gain.
Or to put it on signal route.
My signal condition is:
1. frequency up to 600KHz
2. Use 16 bits 2M ADC to sample
3. switch gain: 1/2, 2
My question is:
1. Can I use analog switch at on op feedback route at this signal condition?
2. if yes, please recommend me best fit product at this signal condition.
3. How good dynamic performance (THD+N)can I achieve at this architecture.
