FUNCTIONAL DESCRIPTION
The AD633 is a low cost multiplier comprising a translinear
core, a buried Zener reference, and a unity-gain connected
output amplifier with an accessible summing node. Figure 1
shows the functional block diagram. The differential X and Y
inputs are converted to differential currents by voltage-to-
current converters. The product of these currents is generated
by the multiplying core. A buried Zener reference provides an
overall scale factor of 10 V. The sum of (X × Y)/10 + Z is then
applied to the output amplifier. The amplifier summing node Z
allows the user to add two or more multiplier outputs, convert
the output voltage to a current, and configure various analog
computational functions.
Inspection of the block diagram shows the overall transfer

ERROR SOURCES
Multiplier errors consist primarily of input and output offsets,
scale factor error, and nonlinearity in the multiplying core. The
input and output offsets can be eliminated by using the optional
trim of Figure 11. This scheme reduces the net error to scale
factor errors (gain error) and an irreducible nonlinearity
component in the multiplying core. The X and Y nonlinearities
are typically 0.4% and 0.1% of full scale, respectively. Scale
factor error is typically 0.25% of full scale. The high impedance
Z input should always reference the ground point of the driven
system, particularly if it is remote. Likewise, the differential X
and Y inputs should reference their respective grounds to
realize the full accuracy of the AD633.
