iC-LG
21-Bit Optical Position Encoder with serial/parallel and sin/cos output.
PLEASE NOTE: USE iC-LGC FOR NEW PROJECTS.
Features
LED power control with a 50mA highside driver.
Differential track evaluation and signal-related hysteresis comparators grant EMI immunity and operation up to 125°C.
High assembly tolerance due to synchronised scanning principle using pre- and post-positioned photo sensors.
13 digital tracks pitched at just 500µm.
2 sine ⁄ cosine analog tracks with enlarged photo sensors and electronic calibration features.
Position data resolution of 16 to 21 bits by on-chip interpolation (by 3-bit flash or 8-bit S&H ADC).
Services external multi-turn encoders and interpolation ICs.
Excellent matching and reliability granted by system-on-chip design with integrated photo sensors.
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.
Output modes: parallel, serial BiSS ⁄ SSI, µC interface.
4 to 5.5V single supply operation, low power consumption.
Options: extended temperature range of -40 to +125°C, custom COB assemblies, reticles and code discs.
