MOTOROLA ANALOG IC DEVICE DATA

Linear Four-Quadrant

Multiplier

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

level–shift 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 are provided to simplify offset

adjustment and improve power supply rejection.
