PGA849: Requesting to suggest any Differential amplifier part.

Dear Team, 

Looking forward to your response,

Hello Maharajan, 

Since the frequency range is high the PGA849 would not be useful here. I will redirect this to the high-speed team. 

All the best,

Hi Maharajan,

We have integrated devices such as the THS3217 that could work in your application. It is a fixed gain, but it can be adjusted if using the integrated power op amp as a driving stage. Another option would be to build a discrete difference amplifier if an integrated device like the THS3217 is limiting.

Hi Ignacio, 

Thank you for the reply, 

I have check the part you have suggested, Does THS3217  this part Supports 100Ω differential input.

Since in the datasheet i can see only 50Ω input impedance, Please refer the below attached Image.

Could you please take a look into this, 

Hoping for the reply from your side as soon as possible, 

Thankyou and best regards, 
Maharajan P

Hi Maharajan,

Yes this device can support 100ohms differentially. Most of the data collected was using a configuration with 50ohms to ground for each input.
