• ### Current consumption of AD8370

Hello everyone,

I am facing issues in using AD8370 in my system. Attached is the schematic diagram for the same.

In the datasheet it is mentioned that the IC uses around 80mA of current. In my system the current consumption of the IC is only 40mA. I have…

hi mr_bill,

what is the a level shifter that you used?

thank you.

• ### AD8370 gain data not matching with what is given in description and figures in datasheet

Hi

I see that AD8370 datasheet gives gain range as given below

Low range: −11 dB to +17 dB
High range: 6 dB to 34 dB

But figure 2 and figure 4 shows that the gain at gain code 0 is

Low gain mode: -24dB

High gain mode: -7dB

Request clarification regarding…

Hello

How to calculate the point where AD8370 has the same gain in both low gain mode and high gain mode. I need to switch smoothly between the two modes (for AGC (automatic gain control) construction). In the datasheet there is only a formula for calculating…

• ### Does running AD8370 with VCCI 3V3 and VCCO 5V save much power?

Hello

In my design I currently run VCCI and VCCO at 5V0.

If I were to run the pre-amplifier at 3V3 (VCCI = 3V3) and keep the output stage at 5V (VCCO=5V), would I expect to see a significant power saving?

Or is the pre-amplifier an insignificant part…
