Wideband Four Quadrant Analog
Multiplier (Voltage Output)
July 1994
Features
Description
• This Circuit is Processed in Accordance to MIL-STD883 and is Fully Conformant Under the Provisions of
Paragraph 1.2.1.
The HA-2556/883 is a monolithic, high speed, four quadrant,
analog multiplier constructed in Intersil’ Dielectrically
Isolated High Frequency Process. The voltage output
simplifies many designs by eliminating the current-to-voltage
conversion stage required for current output multipliers. The
HA-2556/883 provides a 450V/µs output slew rate and
maintains 52MHz and 57MHz bandwidths for the X and Y
channels respectively, making it an ideal part for use in video
systems.
• High Speed Voltage Output. . . . . . . . . . . 450V/µs (Typ)
• Low Multiplication error . . . . . . . . . . . . . . . . 1.5% (Typ)
• Input Bias Currents . . . . . . . . . . . . . . . . . . . . . 8µA (Typ)
• Signal Input Feedthrough . . . . . . . . . . . . . . -50dB (Typ)
The suitability for precision video applications is
demonstrated further by the Y Channel 0.1dB gain flatness
to 5.0MHz, 1.5% multiplication error, -50dB feedthrough and
differential inputs with 8µA bias current. The HA-2556 also
has low differential gain (0.1%) and phase (0.1o) errors.
• Wide Y Channel Bandwidth . . . . . . . . . . . 57MHz (Typ)
• Wide X Channel Bandwidth . . . . . . . . . . . 52MHz (Typ)

Applications
The HA-2556/883 is well suited for AGC circuits as well as
mixer applications for sonar, radar, and medical imaging
equipment. The HA-2556/883 is not limited to multiplication
applications only; frequency doubling, power detection, as
well as many other configurations are possible.

NOTES:
1. Parameters listed in Table 3 are controlled via design or process parameters and are not directly tested at final production. These parameters 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. VZ AC characteristics may be implied from VY due to the use of VZ as feedback in the test circuit.
3. Offset voltage applied to minimize feedthrough signal.

DESIGN INFORMATION (Continued)
The information contained in this section has been developed through characterization by Intersil Semiconductor and is for use as
application and design information only. No guarantee is implied.
Applications Information
Operation at Reduced Supply Voltages
The HA-2556 will operate over a range of supply voltages,
±5V to ±15V. Use of supply voltages below ±12V will reduce
input and output voltage ranges. See “Typical Performance
Curves” for more information.
Offset Adjustment
X and Y channel offset voltages may be nulled by using a
20K potentiometer between the VYIO or VXIO adjust pin A
and B and connecting the wiper to V-. Reducing the channel
offset voltage will reduce AC feedthrough and improve the
multiplication error. Output offset voltage can also be nulled
by connecting VZ- to the wiper of a potentiometer which is
tied between V+ and V-.
Capacitive Drive Capability
When driving capacitive loads >20pF a 50Ω resistor should
be connected between VOUT and VZ+, using VZ+ as the output (see Figure 1). This will prevent the multiplier from going
unstable and reduce gain peaking at high frequencies. The
50Ω resistor will dampen the resonance formed with the
capacitive load and the inductance of the output at pin 8.
Gain accuracy will be maintained because the resistor is
inside the feedback loop.
Theory of Operation
The HA-2556 creates an output voltage that is the product of
the X and Y input voltages divided by a constant scale factor
of 5V. The resulting output has the correct polarity in each of
the four quadrants defined by the combinations of positive
and negative X and Y inputs. The Z stage provides the
means for negative feedback (in the multiplier configuration)
and an input for summation into the output. This results in
the following equation, where X, Y and Z are high impedance differential inputs.

To accomplish this the differential input voltages are first converted into differential currents by the X and Y input transconductance stages. The currents are then scaled by a constant
reference and combined in the multiplier core. The multiplier
core is a basic Gilbert Cell that produces a differential output
current proportional to the product of X and Y input signal currents. This current becomes the output for the HA-2557.
The HA-2556 takes the output current of the core and feeds
it to a transimpedance amplifier, that converts the current to
a voltage. In the multiplier configuration, negative feedback
is provided with the Z transconductance amplifier by connecting VOUT to the Z input. The Z stage converts VOUT to a
current which is subtracted from the multiplier core before
being applied to the high gain transimpedance amp. The Z
stage, by virtue of it’s similarity to the X and Y stages, also
cancels second order errors introduced by the dependence
of VBE on collector current in the X and Y stages.
The purpose of the reference circuit is to provide a stable
current, used in setting the scale factor to 5V. This is
achieved with a bandgap reference circuit to produce a temperature stable voltage of 1.2V which is forced across a NiCr
resistor. Slight adjustments to scale factor may be possible
by overriding the internal reference with the VREF pin. The
scale factor is used to maintain the output of the multiplier
within the normal operating range of ±5V when full scale
inputs are applied.

The open loop transfer equation for the HA-2556 is:

An understanding of the transfer function can be gained by
assuming that the open loop gain, A, of the output amplifier
is infinite. With this assumption, any value of VOUT can be
generated with an infinitesimally small value for the terms
within the brackets. Therefore we can write the equation:

Let’s first examine the Balance Concept as it applies to the
standard multiplier configuration (Figure 2).
Signals may be applied to more than one input at a time as
in the Squaring configuration in Figure 4:
Signals A and B are input to the multiplier and the signal W
is the result. By substituting the signal values into the Balance equation you get:
Here the Balance equation will appear as:

Notice that the output (W) enters the equation in the feedback to the Z stage. The Balance Equation does not test for
stability, so remember that you must provide negative feedback. In the multiplier configuration, the feedback path is
connected to VZ + input, not VZ -. This is due to the inversion
that takes place at the summing node just prior to the output
amplifier. Feedback is not restricted to the Z stage, other
feedback paths are possible as in the Divider Configuration
shown in Figure 3.
The last basic configuration is the Square Root as shown in
Figure 5. Here feedback is provided to both X and Y inputs.

The four basic configurations (Multiply, Divide, Square and

have many uses.
Frequency Doubler
Solving for W yields:
5A
W = ----B
Notice that, in the divider configuration, signal B must remain
≥0 (positive) for the feedback to be negative. If signal B is
negative, then it will be multiplied by the VX- input to produce
positive feedback and the output will swing into the rail.
For example, if ACos(ωτ) is substituted for signal A in the
Square function, then it becomes a Frequency Doubler and
the equation takes the form:
( ACos ( ωτ ) ) × ( ACos ( ωτ ) ) =
5 ( W)
And using some trigonometric identities gives the result:

W = ----- ( 1 + Cos ( 2ωτ ) )

Square Root
Communications
The Square Root function can serve as a precision/wide
bandwidth compander for audio or video applications. A
compander improves the Signal to Noise Ratio for your system by amplifying low level signals while attenuating or compressing large signals (refer to Figure 17; X0.5 curve). This
provides for better low level signal immunity to noise during
transmission. On the receiving end the original signal may
be reconstructed with the standard Square function.
The Multiplier configuration has applications in AM Signal Generation, Synchronous AM Detection and Phase Detection to mention a few. These circuit configurations are shown in Figure 6,
Figure 7 and Figure 8. The HA-2556 is particularly useful in
applications that require high speed signals on all inputs.

Although the X and Y inputs have similar AC characteristics, they
are not the same. The designer should consider input parameters such as small signal bandwidth, ac feedthrough and 0.1dB
gain flatness to get the most performance from the HA-2556.
The Y channel is the faster of the two inputs with a small signal
bandwidth of typically 57MHz verses 52MHz for the X channel.
Therefore in AM Signal Generation, the best performance will be
obtained with the Carrier applied to the Y channel and the modulation signal (lower frequency) applied to the X channel.

Each input X, Y and Z has similar wide bandwidth and input
characteristics. This is unlike earlier products where one
input was dedicated to a slow moving control function as is
required for Automatic Gain Control. The HA-2556 is versatile enough for both.

LIKE THE FREQUENCY DOUBLER YOU GET AUDIO CENTERED AT DC
AND 2FC .
The HA-2556 is able to operate over a wide supply voltage range
±5V to ±17.5V. The ±5V range is particularly useful in video applications. At ±5V the input voltage range is reduced to ±1.4V. The
output cannot reach its full scale value with this restricted input,
so it may become necessary to modify the scale factor. Adjusting
the scale factor may also be useful when the input signal itself is
restricted to a small portion of the full scale level. Here we can
make use of the high gain output amplifier by adding external
gain resistors. Generating the maximum output possible for a
given input signal will improve the Signal to Noise Ratio and
Dynamic Range of the system. For example, let’s assume that
the input signals are 1VPEAK each. Then the maximum output for
the HA-2556 will be 200mV. (1V x 1V / (5V) = 200mV. It would be
nice to have the output at the same full scale as our input, so let’s
add a gain of 5 as shown in Figure 9.

Current Output
Another useful circuit for low voltage applications allows the
user to convert the voltage output of the HA2556 to an output current. The HA-2557 is a current output version offering
100MHz of bandwidth, but its scale factor is fixed and does
not have an output amplifier for additional scaling. Fortunately the circuit in Figure 10 provides an output current that
can be scaled with the value of RCONVERT and provides an
output impedance of typically 1MΩ. The equation for IOUT

Figure 15 shows the HA-2556 configured in an Automatic
Gain Control or AGC application. The HA-5127 low noise
amplifier provides the gain control signal to the X input. This
control signal sets the peak output voltage of the multiplier to
match the preset reference level. The feedback network
around the HA-5127 provides a response time adjustment.
High frequency changes in the peak are rejected as noise or
the desired signal to be transmitted. These signals do not
indicate a change in the average peak value and therefore
no gain adjustment is needed. Lower frequency changes in
the peak value are given a gain of -1 for feedback to the
control input. At DC the circuit is an integrator automatically
compensating for Offset and other constant error terms.
This multiplier has the advantage over other AGC circuits, in
that the signal bandwidth is not affected by the control signal
gain adjustment.

Well, OK a multiplier can’t do nonintegral roots “exactly” but
we can get very close. We can approximate nonintegral
roots with equations of the form:

This function can be easily built using an HA-2556 and a
potentiometer for easy adjustment as shown in Figures 19
and 20. If a fixed nonintegral power is desired, the circuit
shown in Figure 21 eliminates the need for the output buffer
M
amp. These circuits approximate the function VIN
where M
is the desired nonintegral power or root.

By adding a second HA-2556 to the circuit an improved fit
may be achieved with a theoretical maximum error of 0.5%
as shown in Figure 23. Figure 23 has the added benefit that
it will work for positive and negative input signals. This
makes a convenient triangle (±5V input) to sine wave (±5V
output) converter.

Similar functions can be formulated to approximate a SINE
function converter as shown in Figure 22. With a linearly
changing (0 to 5V) input the output will follow 0o to 90o of a
sine function (0 to 5V) output. This configuration is theoretically capable of ±2.1% maximum error to full scale.
