The AD9650 input common mode is 0.9V and the LTC6404-X output common mode is 1.1V for a single 3V or 5V supply. The LTC6404-X must have a -1V VEE to drive the ADC at 0.9V.
I have differential input signal with Vcm=0.9V, Vpp=1.0V i.e. actually span from 0.4V~1.4V.
I want to use LTC6404-2 with close loop gain set to 2V/V then pass the signal to AD9633 for sampling; however, this will require a span from -0.1V to 1.9V…
Dear sir or Madam
Can LTC6404-1 be used as half unity gain(0.5V/V) ?
best regards ,
LTC6404-4 is one FDA capable of driving AD9690-500 (~2Vpp diff out, 2.06V CM, 14 bit specs) running off of 5V or even 3.3V supplies. You can see the operation using LTspice as shown below:

What is the maximum output swing I can get without clipping with a 3.3V / GND asymetrical supply ? I found the datasheet confusing on this point.
I read on datasheet page 4 that minimum V_OUTCMR is 1.1V. Does it mean that I will get clipping if (V_OUT…
I have a single ended signals transmitted from an AC coupled DAC. The DAC has 4 outputs and I am using 2 of the outputs as I and Q (90 degrees offset). In order to drive the ADL5375-15 modulator with a DC biased differential input I am using 2 x DC1147…
