Description
The general purpose sensor signal conditioner iC-TW3 provides highly accurate non contact trimming of three independent sine/cosine sensor signals. The differential output signals can be calibrated to 1 Vpp or to 2 Vpp, alternatively. The internal or an external temperature sensor linked to the chip can influence the gain and offset correction by arbitrary temperature-dependent compensation parameters sourced from a look-up table. For encoder applications an automatic gain and offset control compensates sensor offset voltages and stabilizes the output signal level. The direct connection of sine/cosine encoders, MR sensor bridges or photosensor arrays is possible and supported by a selectable input impedance.
