Circuit function MC1494L is a monolithic analog multiplication IC composed of double-balanced differential amplifier, voltage - current converter circuit,a the general multiplication circuit which can use an external device to set the working conditions. It is capable of 4-quadrant multiplication and it is suitable of the various circuit which the input voltage is the positive and negative 10V. Circuit work In order to scale factor of 10, the resistances of resistors R5, R6 take 30K and 62K, lead terminal 14 is the collector output type.Owing to the current output,it adds the OP amplifier A1 to convert between current and voltage.The bias of IC1 output becomes the A1's positive input.
