Photoelectric Sensor with IO-Link

Triad Semiconductor’s TS8003 is a highly integrated Photoelectric Sensor Analog Front End + Power + Industrial Transceiver IC. It combines an optical source modulated transmit driver, dual high-performance photodiode receive channels, high input voltage DC-DC converter / linear regulators, and user configurable high-voltage IO-Link / binary output stages.  The TS8003 provides a complete mixed-signal interface solution for multiple application modes and the next generation of small sensor form factors.

The TS8003 is available in a tiny 30-bump wafer level chip scale package (WLCSP, 2.6mm x 3mm, 0.5mm pitch).  The device operates from a +9V to +36V nominal supply input and is specified over a -25oC to +85oC operating temperature range.
