Description
The RC4200 analog multiplier has complete compensation
for nonlinearity, the primary source of error and distortion.
This multiplier also has three onboard operational ampliers
designed specically for use in multiplier logging circuits.
These ampliers 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 sacricing 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 coefcient.
