SA5521 Datasheet Lvdt Signal Conditioner

Manufacturer: Philips Semiconductors (now NXP Semiconductors)

Overview: Philips Semiconductors Linear Products Product specification LVDT signal conditioner.

General Description

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.
