    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.
