The Texas Instruments 1191N403RT is a Digital Micromirror Device (DMD) classified as a specialized integrated circuit. It features an 80-lead Low-Carbon Leadless Chip Carrier (LCCC) package with dimensions of 20.7x9.1 mm. Designed for surface mount installation, this component functions as a semiconductor-based spatial light modulator array. The device utilizes individually addressable, tiltable mirror pixels to control light reflection, serving as the core optical engine in digital light processing systems.
This component belongs to the category of DMDs manufactured by Texas Instruments. These devices are distinct from standard driver ICs, acting instead as the physical micromirror array that modulates light. The 1191N403RT specifically denotes a variant within the TI DMD portfolio characterized by its specific lead count and form factor.
