HA2546
Adjusting the scale factor will tailor the control signal, V
X
,
input voltage range to match your needs. Referring to the
simplified schematic and looking for the V
X
input stage, you
will notice the unusual design. The internal reference sets up
a 1.2mA current sink for the V
X
differential pair. The control
signal applied to this input will be forced across the scale
factor setting resistor and set the current flowing in the V
X+
side of the differential pair. When the current through this
resistor reaches 1.2mA, all the current available is flowing in
the one side and full scale has been reached. Normally the
1.67k
internal resistor sets the scale factor to 2V when the
Gain Adjust pins B and C are connected together, but you
may set this resistor to any convenient value using pins 16
(GA A) and 15 (GA C).

FIGURE 3. AUTOMATIC GAIN CONTROL
In Figure 3, the HA-2546 is configured in a true Automatic
Gain Control or AGC application. The HA-5127, low noise op
amp, provides the gain control level to the X input. This level
will set the peak output voltage of the multiplier to match the
reference level. The feedback network around the HA-5127
provides stability and a response time adjustment for the
gain control circuit.
