THS2630: With AMC3330 to convert differential signal 2V to 10V with isolation?

Part Number: THS2630
Other Parts Discussed in Thread: TINA-TI

Tool/software:

Hi Experts,

Customer would like to use AMC3330QDWERQ1 which provide the isolation and output differential signal of 2V and at later stage I will use fully differential amplifier THS2630SDR to convert 2V differential signal to 10V differential signal.

Does it work for my application?

Regards,
Archie A.

    Hello Archie,

      Yes, the customer should be able to use the THS2630 to convert an output differential signal of 2V to 10V. Below is an example via simulation using Tina-TI, I have a 2V differential input signal at AMC3330QDWERQ1 max bandwidth of 375kHz, and set the FDA to a gain of 5V/V as shown in Figure 7-1 with a RF value recommended at 2kOhm. 

      Note: Not sure if 2Vpp, or 4Vpp to 10Vpp or 20Vpp, but customer may change attached file for correct input voltage.

    Thank you,
