21-Bit Optical Position Encoder with Serial/Parallel and Sin/Cos Output – BiSS C.


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.
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, customised COB modules, customised code designs.
