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.
Hello Aldo,
Yes, the Preamp can be used in this way. This resistor configuration, however, will only amplify the difference at a gain of two. When R11=R10 and R8=R9, the gain of the amplifier will be: Vout = (R11/R8)*("Vin+" - "Vin-").

Hey Aldo,
You can find the model for the preamp in the "software" tab of the product page, linked here.
