DESCRIPTION
The CMOS device iC-ML consists of four hall sensors arranged in a line and optimized to read out magnetic tapes with 2.56 mm pole spacing. This sensor array permits error-tolerant adjustment of the magnetic tape, reducing assembly efforts. The integrated signal conditioning unit provides a differential sine/cosine signal at the output.

FEATURES
♦ Linear Hall sensor array for magnetic pole pitch of 2.56 mm
♦ Non-sensitive to magnetic stray fields due to differential
   measurement technique
♦ Interpolator with 8-bit linear resolution of 20 µm
♦ Linear speed up to 5 m/s
♦ Buffered I/O stages for signal outputs
♦ Configuration inputs for operating mode selection
♦ Analog operation modes:
   - sine/cosine signals controlled to 2 Vpp
   - triange or sawtooth signal with selectable amplitude
♦ Digital operation modes:
   - A/B quadrature signals with Z index pulse
   - Counter pulses for external binary counters
♦ Cascading of multiple iC-ML possible for chain operation
   (Evaluation of independent scales x, y, z)
♦ Error signal output for detection of low magnetic field strength
♦ Additional operating modes with reduced power consumption
♦ Standby modus when not enabled
♦ Extended temperature range of -40...+125 °C
