Application Information
Theory of Operation
The HA-2547 is a current output, two quadrant multiplier with
one differential signal channel, V
Y
+ and V
Y
-, and one
differential control channel, V
X
+ and V
X
-. Figure 2 shows a
detailed functional block diagram of the HA-2547. The
differential voltages of channels V
X
and V
Y
are converted to
differential currents. These differential currents are then
multiplied in a circuit similar to a Gilbert Cell multiplier,
producing a differential current product. The differential
product currents are then converted to a single-ended output
current which is typically 2mA,
±
20% at full scale (V
X
= 2V,
V
Y
=
±
5V). A trimmed internal scaling resistor, R
Z
, is
designed to convert the output current to an accurate voltage
by grounding R
Z
(pin 10). R
Z
is trimmed such that at full scale
output current the voltage drop across R
Z
will be
±
5.0V.
