Wideband Linear Four Quadrant 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 electronicgain 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.
