MPY634 is an analog multiplier with the output current being proportional to the product of two input signals X and Y (both AC and DC) . When the input is AC signal, it needs to use isolation transformer, which is not shown in the figure. Taking into account MPY634 computing precision, the maximum of output current is 5mA. Therefore, the output voltage U. Peak - peak value is lOV, the minimum of Rs is 2kΩ.
