6-CH. INCREMENTAL OPTO ENCODER ARRAY
Rev B1, Page 2/13
DESCRIPTION
iC-LTA is a versatile optical sensor IC with integrated
photosensors whose signals are converted into voltages by low-noise transimpedance amplifiers. Precise voltage comparators with hysteresis are used to
generate the digital signals, supplied to the output
pins via differential +/- 4 mA push-pull drivers.
The built-in LED power control with its 40 mA driver
stage permits a direct connection of the encoder
LED. Regardless of aging or changes in temperature
the received optical power is kept constant.
Selection input SEL chooses for three different operating modes: regular A/B operation, A/B operation
with 2-fold interpolation, or analog operation. With
analog operation the amplified signal voltages are
available at the outputs for inspection and monitoring
encoder assembly.
The typical application of iC-LTA are incremental encoders for motor feedback and commutation. To this
end, iC-LTA provides a differential scanning for the
A/B track and the index track Z. The layout of the signal amplifiers is such that there is an excellent paired
channel matching, eliminating the needs for signal
calibration.
Additionally, three more tracks are provided to generate motor commutation information for the U, V and
W outputs, for instance with 120 degree phase shift
to operate 3-phase brushless motors (period count
and phase shift can be varied by the code disc applied).
