THS4521: high common mode voltage

Part Number: THS4521
Other Parts Discussed in Thread: ADC3441

HELLO, my input  signal  is  a  not symmetrical signal ,it is a bipolar signal  bandwidth is 40M,  and it's voltage range is from  -50v  to  450V(ingore the setting in the tina), now i want to use  the circuit below ,using ths4521 to interface to i scale the input  to 1.6vpp 。there is a problem ,the input signal may have high common voltage input about 200V,how should i modify this circuit  to Suppresses high common mode  voltage

I still want to record  the voltage high about  3KV, may be  the common mode voltage of this signal will be up to 1kV,how should i do ?Using  Op amps with high common mode voltage or others?
