请问这款全差分放大器AD8370芯片,差分输入电压、电流有没有限制?差分输出入电压、电流有没有限制?能否在增益34dB情况下,保证400M速率?
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.
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…

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…
Hallo,
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…
