FUNCTIONAL DESCRIPTION
The functional block diagram for the AD532 is shown in Figure
1, and the complete schematic in Figure 2. In the multiplying
and squaring modes, Z is connected to the output to close the
feedback around the output op amp. (In the divide mode, it is
used as an input terminal.)
The X and Y inputs are fed to high impedance differential am-
plifiers featuring low distortion and good common-mode rejec-
tion. The amplifier voltage offsets are actively laser trimmed
to zero during production. The product of the two inputs is
resolved in the multiplier cell using Gilbert’s linearized trans-
conductance technique. The cell is laser trimmed to obtain
V
to obtain low output impedance and make possible self-contained
operation. The residual output voltage offset can be zeroed at
V
grounded.
