Data Sheet September 1998 File Number 2861.3
30MHz, Voltage Output, Two Quadrant Analog Multiplier
The HA-2546 is a monolithic, high speed, two quadrant, analog multiplier constructed in the Intersil Dielectrically Isolated High Frequency Process. The HA-2546 has a voltage output with a 30MHz signal bandwidth, 300V/s slew rate and a 17MHz control bandwidth. High bandwidth and slew rate make this part an ideal component for use in video systems. The suitability for precision video applications is demonstrated further by the 0.1dB gain flatness to 5MHz, 1.6% multiplication error, -52dB feedthrough and differential inputs with 1.2A bias currents. The HA-2546 also has low differential gain (0.1%) and phase (0.1 degree) errors. The HA-2546 is well suited for AGC circuits as well as mixer applications for sonar, radar, and medical imaging equipment. The voltage output simplifies many designs by eliminating the current to voltage conversion stage required for current output multipliers. For MIL-STD-883 compliant product, consult the HA-2546/883 datasheet.

HA-2546 Application Information

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 amplifier. The differential voltages of channel X and Y are converted to differential currents. These currents are then multiplied in a circuit similar to a Gilbert Cell multiplier, producing 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 "product/sum" currents are converted to a singleended current and then converted to a voltage output by a transimpedance amplifier. The open loop transfer equation for the HA-2546 is: (VX+ - VX-) (VY+ - VY-) VOUT = A where; SF - (VZ+ - VZ-)

FIGURE 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 multiplier within the normal operating range of 5V. The scale factor can be defined by the user by way of an optional external resistor, REXT, and the Gain Adjust pins, Gain Adjust A (GA A), Gain Adjust B (GA B), and Gain Adjust C (GA C). The scale factor is determined as follows: 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 k) SF 1.2 (REXT + 1.667k), when REXT is connected to GA B and GA C (REXT is in k) 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. The typical multiplier configuration is shown in Figure 2. The ideal transfer function for this configuration is: VOUT = (VX+ - VX-) (VY+ - VY-) 2 0 + VZ-, when VX 0V , when VX < 0V
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.
Offset Adjustment
The signal channel offset voltage may be nulled by using a 20k potentiometer between VYIO Adjust pins A and B and connecting the wiper to V-. Reducing the signal channel offset will reduce VX AC feedthrough. Output offset voltage can also be nulled by connecting VZ- to the wiper of a 20k potentiometer which is tied between V+ and V-.
Capacitive Drive Capability
When driving capacitive loads >20pF, a 50 resistor is recommended between VOUT and VZ+, using VZ+ as the output (see Figure 2). This will prevent the multiplier from going unstable.
Power Supply Decoupling
Power supply decoupling is essential for high frequency circuits. A 0.01F high quality ceramic capacitor at each supply pin in parallel with a 1F 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.
Adjusting Scale Factor
Adjusting the scale factor will tailor the control signal, VX, input voltage range to match your needs. Referring to the simplified schematic on the front page 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
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.

HA-2546
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) (See Figure 3). 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 5. 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.
Video Fader
The Video Fader circuit provides a unique function. Here Ch B is applied to the minus Z input in addition to the minus Y input. In this way, the function in Figure 6 is generated. VMIX will control the percentage 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 data sheet for additional applications.

Automatic Gain Control
In Figure 4 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
