HA2546/883
Wideband Two Quadrant Analog
Multiplier (Voltage Output)
July 1994
Features
Description
• This Circuit is Processed in Accordance to MIL-STD- The HA-2546/883 is a monolithic, high speed, two quadrant,
883 and is Fully Conformant Under the Provisions of analog multiplier constructed in the Intersil Dielectrically Iso-
Paragraph 1.2.1.
lated High Frequency Process. The HA-2546/883 has a volt-
age output with a 30MHz signal bandwidth, 300V/µs slew
rate and a 17MHz control input bandwidth. High bandwidth
and slew rate make this part an ideal component for use in
video systems. The suitability for precision video applica-
tions is demonstrated further by the 0.1dB gain flatness at
5MHz, 1.6% multiplication error, -52dB feedthrough and dif-
ferential inputs with 1.2µA bias currents. The HA-2546/883
also has low differential gain (0.1% typ.) and phase (0.1o
typ.) errors.

The HA-2546/883 is well suited for AGC circuits as well as
mixer applications for sonar, radar, and medical imaging
equipment. The voltage output of the HA-2546/883 simplifies
many designs by eliminating the current-to-voltage conver-
sion stage required for current output multipliers.

1. Parameters listed in Table 3 are controlled via design or process parameters and are not directly tested at final production. These param-
eters are lab characterized upon initial design release, or upon design changes. These parameters are guaranteed by characterization
based upon data from multiple production runs which reflect lot to lot and within lot variation.
2. Full Power Bandwidth guarantee based on Slew Rate measurement using FPBW = Slew Rate/(2πV
).

Theory of Operation

The HA-2546 is a two quadrant multiplier with the following
three differential inputs; the signal channel, VY+ and VY-, the
control channel, VX+ and VX-, and the summed channel,
VZ+ and VZ-, to complete the feedback of the output ampli-
fier. The differential voltages of channel X and Y are con-
verted to differential currents. These currents are then
multiplied in a circuit similar to a Gilbert Cell multiplier, pro-
ducing a differential current product. The differential voltage
of the Z channel is converted into a differential current which
then sums with the products currents. The differential “prod-
uct/sum” currents are converted to a single-ended current
and then converted to a voltage output by a transimpedance
amplifier.

FIGURE 1.
The open loop transfer equation for the HA-2546 is:
The VX- pin is usually connected to ground so that when VX+
is negative there is no signal at the output, i.e. two quadrant
operation. If the VX input is a negative going signal the VX+
pin maybe grounded and the VX- pin used as the control
input.
(VX+ - VX-) (VY+ - VY-)
- (VZ+ - VZ-)
VOUT = A
SF
where;
The VY- terminal is usually grounded allowing the VY+ to
swing ±5V. The VZ+ terminal is usually connected directly to
VOUT to complete the feedback loop of the output amplifier
while VZ- is grounded. The scale factor is normally set to 2
by connecting GA B to GA C. Therefore the transfer equation
simplifies to VOUT = (VX VY) / 2.
A = Output Amplifier Open Loop Gain
SF = Scale Factor
VX, VY, VZ = Differential Inputs
The scale factor is used to maintain the output of the multi-
plier within the normal operating range of ±5V. The scale fac-
tor can be defined by the user by way of an optional external
Offset Adjustment
resistor, REXT, and the Gain Adjust pins, Gain Adjust A (GA The signal channel offset voltage may be nulled by using a
A), Gain Adjust B (GA B), and Gain Adjust C (GA C). The 20kΩ potentiometer between VYIO Adjust pins A and B and
scale factor is determined as follows:
connecting the wiper to -V. Reducing the signal channel off-
set will reduce VX AC feedthrough. Output offset voltage can
also be nulled by connecting VZ- to the wiper of a 20kΩ
potentiometer which is tied between +V and -V.
SF = 2, when GA B is shorted to GA C
SF 1.2 REXT, when REXT is connected between
GA A and GA C (REXT is in kΩ)
Capacitive Drive Capability
SF 1.2 (REXT + 1.667kΩ), when REXT is
connected to GA B and GA C (REXT is in kΩ)
When driving capacitive loads >20pF, a 50Ω resistor is rec-
ommended between VOUT and VZ+, using VZ+ as the output
(See Figure 1). This will prevent the multiplier from going
unstable.
The scale factor can be adjusted from 2 to 5. It should be
noted that any adjustments to the scale factor will affect the
AC performance of the control channel, VX. The normal input
operating range of VX is equal to the scale factor voltage.
Power Supply Decoupling
Power supply decoupling is essential for high frequency cir-
cuits. A 0.01µF high quality ceramic capacitor at each supply
pin in parallel with a 1µF tantalum capacitor will provide
excellent decoupling. Chip capacitors produce the best
results due to the close spacing with which they may be
placed to the supply pins minimizing lead inductance.
The typical multiplier configuration is shown in Figure 1. The
ideal transfer function for this configuration is:

input voltage range to match your needs. Referring to the
simplified schematic and looking for the VX input stage, you
will notice the unusual design. The internal reference sets up
a 1.2mA current sink for the VX 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 VX+
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
1.67kΩ 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).

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.

This multiplier has the advantage over other AGC circuits, in
that the signal bandwidth is not affected by the control signal
gain adjustment.

A wide range of gain adjustment is available with the Voltage
Controlled Amplifier configuration shown in Figure 4A. and
Figure 4B. Here the gain of the HFA0002 is swept from 20V/
V at a control voltage of 0.902V to a gain of almost 1000V/V
with a control voltage of 0.03V.

The Video Fader circuit provides a unique function as shown
in Figure 5. Here Ch B is applied to the minus Z input in
addition to the minus Y input. VMIX will control the percent-
age of Ch A and Ch B that are mixed together to produce a
resulting video image or other signal.

Many other applications are possible including division,
squaring, square-root, percentage calculations, etc. Please
refer to the HA-2556 four quadrant multiplier for additional
applications.
