Do you need higher slew rate than what the AD8129/30 can provide? If so I would suggest that you look at the ADA4857-1/2 op amp and use it in a difference amplifier configuration, to go from differential input to single ended output…
Hi Hari,Unfortunately we do not support TI products here on Engineerzone. Can you tell us more about your systems specifications so we can suggest an analog part that suits your need.You may want to check LT1819, ADA4857 or LT6411 as a start.Regards,
I attached the AD8022 and ADA4857 SPICE models. These were recently created and tested. The models available in the web were not yet updated thus the results were not very good. The attached models are better so use them instead.
There is a CFTL written for this application,
You cannot change the duty cycle in a square signal.
If you need an output buffer, the ADA4857-1 seems a good part...Regards…
At lower frequencies, an op amp can be used to acheive differential-single ended conversion along with some gain if needed. For example, one recommended configuration for the AD9740 is shown below. Suggested op-amps for the interface are AD8055, AD8057…
I build a Howland current source that can pump bi-directional current up to 1MHz, with maximum output swing to +-10V. The schematic simulated using LTSpice is shown below.
This circuit is also being used in analog dialogue 2009, entitled as,
