IC-LNG_14 Datasheet, PDF (1/30 Pages) IC-Haus GmbH – 16-BIT OPTO ENCODER

iC-LNG 16-BIT OPTO ENCODER ^preliminary
WITH SPI AND SERIAL / PARALLEL OUTPUTS
FEATURES
o Excellent matching and technical reliability thanks to
system-on-chip design with integrated photodiodes
o Gray code scanning (11 digital tracks pitched at 400 µm)
o Sine/cosine analog track with electronic calibration
o Diff. sine/cosine outputs with 1024 CPR (amplitude: 500 mV)
o Position value of up to 16 bits through 6-bit interpolation
o Quadrature signals with 1024, 2048, 4096, 8192, 16384 CPR
o Index signal in phase with B low
o 14-bit parallel position data output
o Serial data readout in 1 µs cycles at 16 MHz clock frequency
o SPI interface for configuration and position data output
o 3.3 V-compatible SPI and I/O ports
o LED current control for a constant receive power
(50 mA highside driver, sin²+cos² or sum)
o Permanent parity monitoring of the internal RAM bits
o Alarm for configuration and illumination errors (end of life)
o Temperature range from -40°C to 110°C
o Small outline, 30-pin optoBGA package for SMT
o Illumination: iC-SN85 BLCC SN1C (850 nm encoder LED)
o Code discs:
LNG1S 42-1024 (1024 PPR, ∅ 42 mm/18 mm),
LNG2S 25-512 (512 PPR, ∅ 24.8 mm/2 mm)
