THEORY OF OPERATION
A block diagram of the AD598 along with an LVDT (Linear
Variable Differential Transformer) connected to its input is
shown in Figure 5. The LVDT is an electromechanical trans-
ducer whose input is the mechanical displacement of a core and
whose output is a pair of ac voltages proportional to core posi-
tion. The transducer consists of a primary winding energized by

an external sine wave reference source, two secondary windings
connected in series, and the moveable core to couple flux be-
tween the primary and secondary windings.
The AD598 energizes the LVDT primary, senses the LVDT
secondary output voltages and produces a dc output voltage
proportional to core position. The AD598 consists of a sine
wave oscillator and power amplifier to drive the primary, a de-
coder which determines the ratio of the difference between the
LVDT secondary voltages divided by their sum, a filter and an
output amplifier.
The oscillator comprises a multivibrator which produces a
triwave output. The triwave drives a sine shaper, which pro-
duces a low distortion sine wave whose frequency is determined
by a single capacitor. Output frequency can range from 20 Hz to
20 kHz and amplitude from 2 V rms to 24 V rms. Total har-
monic distortion is typically –50 dB.
The output from the LVDT secondaries consists of a pair of
sine waves whose amplitude difference, (V

), is proportional
to core position. Previous LVDT conditioners synchronously
detect this amplitude difference and convert its absolute value to
