Hello, I have several questions about analog multipliers.
The AD633, with respect to AN-202 and thinking about the path of return currents, is the internal integrator of the output amplifier referred to -VE supply, as in the AD534? The schematic is not available anywhere for me to look myself.
The current output mode of the AD633 and AD534, I am curious as to how this works regarding summing multiple currents (say from 2 multipliers in current out mode) into the virtual ground node of an opamp integrator. In theory (and simulation) there are no concerns, but I wonder whether the current sensing is affected at all in this configuration?
Huge thanks to anyone who can help me with these questions!
