Wideband Linear
FourĆQuadrant Multiplier
The MC1495 is designed for use where the output is a linear product
of two input voltages. Maximum versatility is assured by allowing the
user to select the level shift method. Typical applications include:
multiply, divide*, square root*, mean square*, phase detector,
frequency doubler, balanced modulator/demodulator, and electronic
gain control.
• Wide Bandwidth
• Excellent Linearity:
2% max Error on X Input, 4% max Error on Y Input Over
Temperature
1% max Error on X Input, 2% max Error on Y Input at + 25°C
• Adjustable Scale Factor, K
• Excellent Temperature Stability
• Wide Input Voltage Range: ± 10 V
• ±15 V Operation
*When used with an operational amplifier.
