HA-2546 Data Sheet September 1998 File Number 2861.3 30MHz, Voltage Output, Two Quadrant Analog Multiplier Features 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/µs 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 1.2µA bias currents. The HA-2546 also has low differential gain (0.1%) and phase (0.1 degree) errors. • Low Multiplication error . . . . . . . . . . . . . . . . . . . . . . .1.6% • High Speed Voltage Output . . . . . . . . . . . . . . . . . 300V/µs • Input Bias Currents. . . . . . . . . . . . . . . . . . . . . . . . . . 1.2µA • Signal Input Feedthrough . . . . . . . . . . . . . . . . . . . . . -52dB • Wide Signal Bandwidth . . . . . . . . . . . . . . . . . . . . . 30MHz • Wide Control Bandwidth. . . . . . . . . . . . . . . . . . . . . 17MHz • Gain Flatness to 5MHz. . . . . . . . . . . . . . . . . . . . . . 0.10dB Applications • Military Avionics The HA-2546 is well suited for AGC circuits as well as mixer applications for sonar, radar, and medical imaging equipment.

VX SMALL SIGNAL RESPONSE HA-2546 Application Information 16 NC 1 Theory Of Operation REF 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. NC 2 15 NC 3 14 NC 4 X VY + 5 + 6 V- - - (VX+ - VX-) (VY+ - VY-) where; SF 11 V+ 7 8 + Σ - 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 kΩ) SF ≅ 1.2 (REXT + 1.667kΩ), when REXT is connected to GA B and GA C (REXT is in kΩ) 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 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. 6 - Z + 10 9 VOUT 50Ω 1kΩ 50pF FIGURE 2. - (VZ+ - VZ-) A = Output Amplifier Open Loop Gain SF = Scale Factor VX, VY, VZ = Differential Inputs 12 Y The open loop transfer equation for the HA-2546 is: VOUT = A 13 VX + + 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 20kΩ 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 20kΩ potentiometer which is tied between V+ and V-. Capacitive Drive Capability When driving capacitive loads >20pF, a 50Ω 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 0.01µF 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. 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 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 1.67kΩ 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) (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. 1 REF NC 2 15 NC 3 14 NC 4 13 VX + 16 NC REF 16 NC 1 NC 2 15 NC 3 14 NC 4 + X VY + 5 6 + - - 13 + X VY + 5 + 12 - 6 Y - 12 Y 11 V+ 11 V+ V- 7 V- 7 + Σ - 8 - Z + Σ - 10 8 + Z - 10 + 9 VOUT 9 VOUT 50Ω 1N914 10kΩ 1K MULTIPLIER, VOUT = VXVY / 2V SCALE FACTOR = 2V 10kΩ 5kΩ 1 +15V - 0.1µF 0.01µF + HA-5127 16 3.3V 4.167K REF 20kΩ 0.1µF NC 2 15 NC 3 14 NC 4 13 VX + NC FIGURE 4.

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.
