18-Bit Optical Position Encoder with SPI, Serial / Parallel and FlexCount® Output

iC-LNB is an optoelectronic encoder IC for absolute linear and angle measuring systems, such as glass scales and encoders. Photodiodes, amplifiers, and comparators, the entire signal conditioning unit, and interfaces for position data output have been monolithically integrated into the device.

By help of the unique FlexCount circuit any angle resolution between 4 to 218 angle steps per revolution can be preset for the incremental signals and the absolute position value.
