21-BIT OPTICAL POSITION ENCODER WITH

SERIAL/PARALLEL AND SIN/COS OUTPUT

iC-LG is an optoelectronic encoder iC for absolute linear

Applications

or angular measuring systems, such as glass scales and shaft

encoders. Photosensors, amplifiers and comparators, the entire

signal conditioning unit and interfaces for the position data out-

put are monolithically integrated on the chip.

– Optical high-resolution absolute position encoders

– Analog and digital moto feedback systems

– Robotics, tooling machines, servo motors

Features

– Excellent matching and reliability granted by system-on-chip

design with integrated photosensors

– Services external multiturn encoders and interpolation ICs

– LED power control with a 50 mA highside driver

– Differential track evaluation and signal-related hysteresis

comparators grant EMI immunity and operation up to 125 °C

– High assembly tolerance due to synchronized scanning prin-

ciple using pre- and post-positioned photosensors

– 13 digital tracks pitched at just 500 µm

– 2 sine/cosine analog tracks with enlarged photosensors and

electronic calibration features

– Position data resolution of 16 to 21 bits by on-chip interpola-

tion (by 3-bit flash or 8-bit S&H ADC)

– Adjustable on-chip temperature sensor with a min/max alarm

– Operational monitoring with alarm output for missing code,

corrupted single/multiturn data (disc error), EEPROM link

error, illumination error (end of life), out-of-range temperature

– Interface modes: parallel encoder, serial BiSS/SSI, µC

– 4 to 5.5 V single supply operation, low power consumption

– Options: extended temperature range of -40 to +125 °C, cus-

tomized COB assemblies, reticles and code discs
