Optical Encoder: iC-LNG 14.06.2011
16-Bit Optical Encoder with SPI and Serial/Parallel Outputs
iC-LNG is an optoelectronic encoder IC for absolute linear and angle measuring systems. Photosensors, amplifiers, and comparators, an LED power control and an adjustable signal conditioning unit have been monolithically integrated into the device, as have the necessary interfaces for configuration and data output.

iC-LNG derives the position data from an analog sine/cosine track and 10 or 11 Gray-coded digital tracks. Using the integrated 6-bit flash interpolator absolute position data of up to 16 bits can be generated in real time. Output is through an SPI interface, a fast shift register, or a 14-bit parallel interface.

iC-LNG also has incremental encoder quadrature signals with an index and conditioned sine/cosine signals from the analog track at its disposal. The number of pulses for the quadrature signals can be varied.
