iC-TW3
SENSOR SIGNAL CONDITIONER WITH
TEMPERATURE COMPENSATION AND LINE DRIVER
Rev B1, Page 2/24
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 correc-
tion by arbitrary temperature-dependent compensa-
tion parameters sourced from a look-up table.
For encoder applications an automatic gain and off-
set 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.
