Product Number: ad534
Hello,
I'm trying to understand the input stages of the AD534 multiplier.
On the datasheet (Fig 1), there are 3 "op*amps" named "V-TO-1" for each differential inputs X,Y and Z and I don't understand what that means.
What is the output value of these op amps ? Only X1-X2, Y1-Y2 and Z1-Z2 ?
In this case, why the 0.75 (I guess a gain of 3/4) attenuation is not the the formula on the Z inputs ? Is this specific op amp output transfer function is (Z1-Z2)/0.75 ?
It is not clear what the actual transfer function is for the Z inputs, especially with this 0.75 attenuation. It should be taken in account if feedback is applied, but it does not seems to be the case.
Thanks in advance,
Jerome.
