  • 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


    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…

  • AD8370 gain modes


    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?


    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…

  • AD8370 Noise Figure at different Loads


    i have a question regarding Noise Figure chart (Figure 45).
    What about different RLoads instead of 100 Ohm?
    I have 2054 Ohm Load and Power gain is much smaller as at 100 Ohm.
    At gain code 15 in example power gain is -11.67dB for 2054R Load.
    Will noise…
