1 / 23 page www.fairchildsemi.com REV. 1.2.1 6/14/01 Features • 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 Applications • Low distortion audio modulation circuits • Voltage-controlled active filters • Precision oscillators Description 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. 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.
