THS7002: PRE AMP used as a "diferential" LPF

Part Number: THS7002
Other Parts Discussed in Thread: TINA-TI

Hi!

Can the "PRE AMP" of the THS7002 be used as an "LPF subtracter"? Such as represented in the diagram.

The inputs "Vin +" and "Vin -" would have a DC value (of the order of 4 Vdc) that is wanted to cancel, but keep (and amplify x4) the difference between "Vin +" and "Vin -".

Thank you. Regards!

Aldo.
