Linear Position Sensor IC from iC-Haus
June 22, 2006
The iC-ML from iC-Haus GmbH, Bodenheim, Germany, is an integrated magnetic linear position sensor/encoder in a TSSOP20 package. The circuit contains 4 Hall sensors to generate analog sine/cosine signals at a pole pitch of 2.56 mm as well as integrated signal conditioning with an ADC and output interfaces. Three configuration inputs allow 26 modes of operation for position evaluation of the magnetic tape placed above the chip. In addition to the pure analog signals, the iC-ML also uses the signals to generate output signals with 6-, 7-, or 8-bit resolution for resolutions of 20 µm and up to 256 linear steps.
