Thank You for your reply.
I don't give input signal, I just solder ADA4807 on the PCB, and I have try another ADA4807, but all of them generate heat .
when I use AD8671 or ADA4841, they are normal. they have same the define of Pin.
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…
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…
I'm not an amplifier nor a clocking expert, but here are some comments.
