iC-LGC
21-BIT OPTICAL POSITION ENCODER WITH
SERIAL/PARALLEL AND SIN/COS OUTPUT
iC-LGC is an optoelectronic encoder iC for absolute position
sensors. Photosensors, amplifiers and comparators, the entire
signal conditioning and data processing unit and fast I/O inter-
faces are monolithically integrated on the chip.
Features
• System-on-chip design with integrated photosensors
• Excellent matching and reliability
• Differential scanning for EMI immunity and operation
up to 125 °C
• Enlarged assembly tolerance due to pre-positioned
and post-positioned code scanning
• 13 digital tracks pitched at just 500 μm
• 2 sine/cosine tracks with analog signal conditioning
• Singleturn resolution of 16 to 21 bits by 3-bit flash or
8-bit S&H ADC
• Multiturn data processing via 2-pin A/B or SSI interface,
embedded low power counter for battery supply
• LED power control with a 50 mA highside driver
Applications
• Absolute position encoders for safety-related controls
• Analog and digital motor feedback systems
• Robotics, tooling machines, servo drives
• Adjustable temperature sensor with min/max alarm
• Operational monitoring and alarm/warning messaging:
missing code step, disc data error, configuration error,
LED end-of-life, out-of-range temperature
• Safety features: CRC-protected setup with verification,
CRC-protected data output with life counter
• Operating modes: hardware encoder (up to 16 bits), serial
encoder (SSI, BiSS C), parallel encoder (8-bit parallel µC)
• 4 to 5.5 V single supply operation, low power consumption
• Small-outline optoBGA or BLCC package for SMT
• Available accessories: LED lamps and code discs
• Options: extended temperature range of -40 to +125 °C,
customized COB modules, customized code designs
