I'm not an amplifier nor a clocking expert, but here are some comments.
I am using an ADA4807 as a unity gain buffer, with a +5V and -2.5V supplies. The +ve input is ac coupled to a signal that varies between 17V and 19V @ 250kHz. I have a 100k resistor to ground on the +ve input also. If I simulate this circuit using LTspice…
Try ADA4940 or ADA4807. Also, please see Applications Information Section of the AD4003 datasheet.
I'm building a precision voltage generator and I'm using a DAC to drive the ADA4841 which is in a voltage follower configuration.
Previously it was the ADA4807, but it had some issues like: powering the unit from the USB and batteries…
Most electronic devices today uses Multilayer ceramic capacitors because of the advantage in size, low ESR and low ESL.You can use a Multi-layer ceramic capacitor as a substitute for the tantalum capacitor depending on your application.
