From my customer:
We are interesting in the AD8347 For A low power consumption application in the L band frequency domain (1.3 G-1.7 G) and with Vsource of 2.8 V
I have the following questions :
1- When the DC OFFSET COMPENSATION mechanism is disabled ,what will be The DC offset level at the output BB amplifier ?
t's mentioned in the DS that The output DC offset with the DC OFFSET COMPENSATION mechanism is typical -+50 mV,will it get worse ?
2. The data sheet tells about the current level for Vsource = 5 V , what is the current level of the device for Vsource = 2.8 V (min , typical ,max ) ?
Why there is such a change in the current level as mentioned in the DS from min to max ? is it for Temperature changes ?
3. Can ANALOG DEVICES create a custom made chip with lower current and lower power consumption? we can compromise on the other specifications like a smaller Gain or Higher NF level .
