The MC1494 is designed for use where the output voltage is a linear product of two input voltages. Typical applications include: multiply, divide, square root, mean square, phase detector, frequency doubler, balanced modulator/ demodulator, electronic gain control.
The MC1494 is a variable transconductance multiplier with internal levelshift circuitry and voltage regulator. Scale factor, input offsets and output offset are completely adjustable with the use of four external potentiometers. Two complementary regulated voltages of MC1494 are provided to simplify offset adjustment and improve power supply rejection.
