Linearity Error
Maximum Demodulator Input
RMS value of the AC voltage at the oscillator output pin. This output is referenced to VREF/2
and is a function of VREF.
The Total Harmonic Distortion (THD) of the oscillator output with no load. This is not a
critical specification in LVDT/RVDT systems. This figure could be 15% or more without
affecting system performance.
A measure of the interchangeability of NE/SA/SE5521 parts, not a characteristic of any one
part. It is the degree to which the oscillator output of a number of NE/SA/SE5521 samples
will vary from the median of that sample.
Another measure of the interchangeability of individual NE/SA/SE5521 parts. This is the
degree to which the oscillator frequency of a number of NE/SA/SE5521 samples will vary
from the median of that sample with a given timing capacitor.
A measure of how the oscillator amplitude varies with ambient temperature as that
temperature deviates from a 25°C ambient.
A measure of how the oscillator frequency varies with ambient temperature as that
temperature deviates from a 25°C ambient.
The degree to which the oscillator frequency will vary as the reference voltage (VREF)
deviates from +10V.
Minimum load impedance for which distortion is guaranteed to be less than 5%.
The degree to which the DC output of the demodulator/amplifier combination matches a
change in the AC signal at the demodulator input. It is measured as the worst case
nonlinearity from a straight line drawn between positive and negative fullscale end points.
The maximum signal that can be applied to the demodulator input without exceeding the
specified linearity error.
