iC-LO is a triangulation sensor from German fabless chip company iC-Haus.
For use in diffuse reflective photoelectric sensors, the IC includes a linear array of 129 photodiodes, signal conditioning circuitry, a 1.2A LED driver, and a microcontroller interface.
"Besides the iC-LO, all that is needed to create a triangulation measurement setup are a transmitting LED and a low-cost microcontroller," said the firm.
Two AC amplifiers enable interference and ambient light suppression with a dynamic range of up to 100dB, claims the firm and adding an optical filter can push ambient light suppression of up to 100,000 lux.
Measurement rates are up to 13.9kHz, and these can be averaged by a digital filter.
LED driver pulse duration is set through an SPI interface and an external laser diode driver can be added for laser triangulation.
Operation is from 4.5 to 5.5V through -40 to +85°C, the 5pin optoBGA package requires a 4x9mm footprint, and there is a demo board plus evaluation software.
