LTC6244 Low Noise AC Difference Amplifier

Aug 22nd 2006
Piezoelectric and LVDT (Linear Variable Differential Transformer) sensors provide differential ac output signals. In addition to a standard difference amplifier a secend amplifier can be used as a dc servo amplifier to force an output dc bias potential in single supply applications. This difference amplifier is dc coupled but ...

LVDT Signal Conditioning

Aug 24th 1998
An LVDT transformer is exited with a fixed frequency sine wave. The distance of displacement of the movable core will change the amplitude of the transformer output which is is converted to a dc voltage by the LT1967 True RMS converter. The direction of the core movement is indicated by the phase shift of the sine wave and is ...
