THEORY OF OPERATION
The transfer function for the MPY534 is:
(X
– X
) (Y
– Y
)
V
OUT
= A – (Z
1
– Z
2
)
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, Z
= V
and Z
2
= 0. The quantity
within the brackets then reduces to:
(X
– X
) (Y
– Y
)
SF
– (V
OUT
– 0) = 0
This approach leads to a simple relationship which can be
solved for V
OUT
.
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:
R
