Dear Sir/Madam,

I am just studying for your AD8362.

And I red page.22-23 "ALTERING THE SLOPE" on your datahseet AD8362'.

So I would like to know as following matters.

Due to that I cannot catch some technical info on there....

1)

After the VRMS-signal convert to DC, eg;how can I shift it to 0.07V ~ 1.2V?

Do you have the sample or recommend circuilt solution?

I dont have the good idea for this matter fixing.

2)

Please let me know how can I adjust VTGT?

What's the way?

Do you have such as the application note?

3)

eg;How can I set up 200mV/dB slope?

Can you instruct it to me?

I could not the understand well by the explanation of datasheet only.

Thanks Kaos

You can change the slope and output scaling using the circuit in Figure 55 (Rev D datasheet) along with equation 15 on the next page. Decide on the desired slope that you want (200 mV/dB). Then pick a reasonable value for the R2 Resistor (say 2K).. Then plug these two values (Sd=200, R2=2K) into equation 15 and a value for R1 will come out.

If you want to change Vtgt, use a resistor divider between Vref and Vtgt (there are components on the eval board for doing this). I recommend a Vtgt of 0.625 V
