NE5521N LVDT SIGNAL CONDITIONER IC
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.
Single supply 5V to 20V, or dual supply 2.5V to 10V
Oscillator frequency 1kHz to 20kHz
Capable of ratiometric operation
Low power consumption (182mV typ)
