Product specification  
LVDT signal conditioner  
NE/SA/SE5521  
DESCRIPTION  
PIN CONFIGURATIONS  
The NE/SA/SE5521 is a signal conditioning circuit for use with  
Linear Variable Differential Transformers (LVDTs) and Rotary  
Variable Differential Transformers (RVDTs). The chip includes a low  
distortion, amplitude-stable sine wave oscillator with programmable  
frequency to drive the primary of the LVDT/RVDT, a synchronous  
demodulator to convert the LVDT/RVDT output amplitude and phase  
to position information, and an output amplifier to provide  
amplification and filtering of the demodulated signal.
