Analog Multiplier

Description

Features

The RC4200 analog multiplier has complete compensation

for nonlinearity, the primary source of error and distortion.

This multiplier also has three onboard operational ampliﬁers

designed speciﬁcally for use in multiplier logging circuits.

These ampliﬁers are frequency compensated for optimum

AC response in a logging circuit, the heart of a multiplier,

and can therefore provide superior AC response.

• High accuracy

• Nonlinearity – 0.1%

Temperature coefﬁcient – 0.005%/°C

• Multiple functions

• Multiply, divide, square, square root, RMS-to-DC

conversion, AGC and modulate/demodulate

• Wide bandwidth – 4 MHz

• Signal-to-noise ratio – 94 dB

The RC4200 can be used in a wide variety of applications

without sacriﬁcing accuracy. Four-quadrant multiplication,

two-quadrant division, square rooting, squaring and RMS

conversion can all be easily implemented with predictable

accuracy. The nonlinearity compensation is not just trimmed

at a single temperature, it is designed to provide compensa-

tion over the full temperature range. This nonlinearity

compensation combined with the low gain and offset drift

inherent in a well-designed monolithic chip provides a very

high accuracy and a low temperature coefﬁcient.

Applications

• Low distortion audio modulation circuits

• Voltage-controlled active ﬁlters

• Precision oscillators
