I'm trying to simulate on LTSPICE an AGC loop made by components whose supply is 3.3V max. After discovered here that my original choice for VGA, AD8330, has convergence problems on LTSPICE, I found interesting for me the AD8337 component, whose supply…
I tried to simulate AD8337 with it's model provided in ADI website. But in the Orcad 16.6 PSpice,I get error ERROR(ORPSIM-16366): Line too long. Limit is 132 characters.
How can I run the simulation smoothly?
I am planning to use the AD8337 in inverting gain configuration with a preamp gain of -1/2 (Figure 67 in the datasheet, Rfb1=200, Rfb2=100) resulting in a total gain range from -12 to 12dB.Since my input signal will be a multi sine signal with frequencies…
The AD8337 has an exposed heatsink pad on the underside of the package. However, the datasheet doesn't say anything about how to connect this on the PCB. Should I connect it to GND, VSS, or what? What are the internal connections for this pad?
I'm looking for the package and footprint of the AD8337 VGA to be used in Altium Designer. At this moment, I'm not able to find any library that contains this component. Is there any way to obtain this?
Thank you very much
What is the (noninverting) input impedance of AD8337?
And another question: someone has asked about its dynamic range, and got a detailed answer, but in the end it claimed:
"3. The AD8337 was developed and characterized as a differential-output…
Hi, how could i get the spec the output dynamic range of AD8337 in its datasheet? thanks.
I have imported your spice model in LTspice and connected it as in Figure 65 of the datasheet. However, the output signal does not behave as expected. I have tried the same circuit in PSpice with the same result.
Amplifying a signal from a TIA powered from 5V. The signal swings from ~0V up to ~3V depending on received light intensity. I am looking to DC couple the TIA to the AD8337 and would like to ask and verify the following:
Regarding the Single Supply…
