I am going to use the AD8318. Do you have any application note for Vout temperature compensation? By TADJ pin? By TEMP pin? any compensation circuit?
The two evaluation boards correspond to two separate part numbers. AD8318-EVALZ is for AD8318, while AD8318-EP-EVALZ is for AD8318-EP (enhanced product). Please see each product's datasheet for further details.
Unfortunately, there is not a SPICE model nor a tool to simulate the AD8318.
If this request is for evaluation purposes, I recommend acquiring an ADI evaluation board for the AD8318 and evaluating it in the lab.

We provide gerber files for the AD8318 evaluation board on the product webpage. (http://www.analog.com/en/specialty-amplifiers/log-ampsdetectors/ad8318/products/EVAL-AD8318/eb.html). This along with the 'Evaluation board' section on the datassheet should…
Hi Will, what do you mean of the description "high power signals cause a strange waveform on the output of the log amp." ? Is your application of AD8318 is for partial discharge detector? How about the AD8318 usage now?
The part can’t handle the direct dc connection. It can handle the ac swing. If you look at figure 5 on page 8, in the AD8318 datasheet, you see that 1.67 volts corresponds to an input power of ~ -53 dBm and the AD8318 will still try and close the loop…
Although I have never exercised the ADL5330/AD8318 in pulsed mode myself, my recommendation is to try the circuit with the AD8318 CLPF pin (pin 5) open. The noise floor of the AD8318 may be slightly higher but this may be compensated by the narrow…
