iC-LG is an optoelectronic encoder iC for absolute linear 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 output are monolithically integrated on the chip.
• Optical high-resolution absolute position encoders
• Analog and digital moto feedback systems
• Robotics, tooling machines, servo motors
The differential evaluation of all tracks enables operation at high ambient temperatures. Scanning uses pre- and post-positioned photosensors for each track, permitting high adjustment tolerances during system assembly. An integrated LED power control with a highside driver guarantees illumination regardless of temperature or aging effects.
The chip features offset and amplitude calibration for the analog output signals also fed to the integrated 3-bit flash and the 8-bit SAR interpolators.
External multiturn sensor slaves can be operated via an SSI interface. Here, iC-LG is master and synchronizes all data to produce a contiguous, single-step-proof position data word. Additionally, temperature data is available from an on-chip sensor, featuring adjustable high/low alarms to monitor encoder and drive operation.
The fast BiSS interface (SSI mode is optional) and an 8-bit microcontroller interface are available to output the position data and to configure the chip. An external EEPROM can also provide setup and OEM data.
