DESCRIPTION
The MPY634 is a wide bandwidth, high accuracy, four- quadrant analog multiplier. Its accurately laser-trimmed multiplier characteristics make it easy to use in a wide variety of applications with a minimum of external parts, often eliminating all external trimming. Its differential X, Y, and Z inputs allow configuration as a multiplier, squarer, divider, square-rooter, and other functions while maintain- ing high accuracy. The wide bandwidth of this new design allows signal processing at IF, RF, and video frequencies. The internal output amplifier of the MPY634 reduces design complexity compared to other high frequency mul- tipliers and balanced modulator circuits. It is capable of performing frequency mixing, balanced modula- tion, and demodulation with excellent carrier rejection. An accurate internal voltage reference provides precise setting of the scale factor. The differential Z input allows user-selected scale factors from 0.1 to 10 using external feedback resistors.

SBFS017A www.ti.com TYPICAL PERFORMANCE CURVES (CONT) TA = +25°C, VS = ±15VDC, unless otherwise noted. THEORY OF OPERATION The transfer function for the MPY634 is: VOUT = A – (Z1 – Z2) where: A = open-loop gain of the output amplifier (typically 85dB at DC). SF = Scale Factor. Laser-trimmed to 10V but adjustable over a 3V to 10V range using external resistors. X, Y, Z are input voltages. Full-scale input voltage is equal to the selected SF. (Max input voltage = ±1.25 SF). An intuitive understanding of transfer function can be gained by analogy to the op amp. By assuming that the open-loop gain, A, of the output operational amplifier is infinite, 1 – X2) (Y1 – Y2) SF inspection of the transfer function reveals that any VOUT can be created with an infinitesimally small quantity within the brackets. Then, an application circuit can be analyzed by assigning circuit voltages for all X, Y and Z inputs and setting the bracketed quantity equal to zero. For example, the basic multiplier connection in Figure 1, Z 1 = VOUT and Z2 = 0. The quantity within the brackets then reduces to: – (VOUT – 0) = 0 This approach leads to a simple relationship which can be solved for VOUT to provide the closed-loop transfer function. The scale factor is accurately factory adjusted to 10V and is typically accurate to within 0.1% or less. The scale factor may be adjusted by connecting a resistor or potentiometer between pin SF and the –V S power supply. The value of the external resistor can be approximated by: SF 81 0 1 2 1 6 1 8 2 0 Positive or Negative Supply (V) INPUT/OUTPUT SIGNAL RANGE vs SUPPLY VOLTAGES Peak Positive or Negative Signal (V) Output, RL ≥ 2kΩ All inputs, SF = 10V –10 INPUT DIFFERENTIAL-MODE/ COMMON-MODE VOLTAGE –12 12 –55 1 0–10 Specified Accuracy VS = ±15V Functional Derated Accuracy VCM VDIFF 800 700 600 500 400 300 200 100 –20 0 60 100 140 Temperature (°C) BIAS CURRENTS vs TEMPERATURE (X,Y or Z Inputs) Bias Current (nA) 20–40 40 80 120 Scaling Voltage = 10V Scaling Voltage = 3V –60
