ADHV4702 ramp signal with high current output

Hello,

I have found a document that is related to your concern.
Please see link below:
https://www.analog.com/en/technical-articles/increase-amplifier-output-drive-using-a-push-pull-amplifier-stage.html

In addition, I have contacted the responsible Apps Engr of this part to check if we have additional reference for the said application.

Thanks and regards.

Thanks for the reply. It would be helpful if some more documents available related to my design requirement.

Hello,

Here is are some additional information I have from the responsible Apps Engr of this part.

The N channel and P channel push-pull MOSFETs are as follows:

N-Channel: IXTP3N120 – Datasheet: http://ixapps.ixys.com/DataSheet/IXTA3N120.pdf

P-Channel: IXTP10P50P – Datasheet: http://ixapps.ixys.com/DataSheet/DS99911D(IXTA-TH-TP-TQ10P50P).pdf

Theoretically, you could increase the output current drive capability by select higher power MOSFETs. The default MOSFETs are also able to handle a higher output current based on the specs in the datasheet. In addition, thermal management would be extremely critical when you are trying to get a higher output current.

Thanks and regards.

Thanks for the reply. It is clear to me that we can use MOSFET's IXTP3N120 and IXTP10P50P.

Figure 64 of ADHV4702 datasheet shows the configuration of high current output.

Resistors R3 and R5 values are not mentioned.

Can you suggest which values should be chosen for the resistors R3 and R5 when I am using the above mentioned MOSFET'S.

My output signal range will vary from -100 Volts to +100 Volts and output current ranging in terms of Amperes.

As mentioned that thermal management is also critical. Can you share some document related to the thermal management of IC ADHV4702.
