DESCRIPTION

The MPY534 is a high accuracy, general purpose four-quadrant analog multiplier. Its accurately laser trimmed transfer characteristics make it easy to use in a wide variety of applications with a minimum of external parts and trimming circuitry. Its differential X, Y and Z inputs allow configuration as multiplier, squarer, divider, square-rooter and other functions while maintaining high accuracy. The wide bandwidth of this new design allows accu- rate signal processing at higher frequencies suitable for video signal processing. It is capable of performing IF and RF frequency mixing, modulation and demodu- lation with excellent carrier rejection and very simple feedthrough adjustment. An accurate internal voltage reference provides pre- cise setting of the scale factor. The differential Z input allows user selected scale factors from 0.1 to 10 using external feedback resistors.

THEORY OF OPERATION The transfer function for the MPY534 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 resistor. X, Y, A 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 an op amp. By assuming that the open-loop gain, A, of the output amplifier is infinite, inspection of the transfer function reveals that any V OUT can be created with an infinitesimally small quantity within the brackets. Then, SF 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, Z1 = 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 . 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: RSF = 5.4kΩ SF 10 – SF SF
