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.
• Operates with ±15 V Supplies
• Excellent Linearity: Maximum Error (X or Y) ±1.0 %
• Wide Input Voltage Range: ±10 V
• Adjustable Scale Factor, K (0.1 nominal)
• Single–Ended Output Referenced to Ground
• Simplified Offset Adjust Circuitry
• Frequency Response (3.0 dB Small–Signal): 1.0 MHz
• Power Supply Sensitivity: 30 mV/V typical
