Profile: East Texas Integrated Circuits is a supplier of integrated circuits for robotics and motion control industries. Our product line includes line driver circuits, signal conditioning circuits, interpolation circuits, logic output photo ICs, three channel comparator, phototransistors and three channel amplifiers. Our ET2010 analog signal processor is a monolithic bipolar ASIC designed to transform nanoamp-level differential photocurrents into 1Vpp sinewaves that are suitable for interpolation. Our three channel comparator devices are designed as receiver circuits for the phototransistor signals available in some optical encoders.
