TSL210

TSL210 Datasheet

The TSL210 linear sensor array consists of five sections of 128 photodiodes, each with associated charge amplifier circuitry, running from a common clock. These sections can be connected to form a contiguous 640 x 1 pixel array. Device pixels measure 120 um H by 70 um W with 125-um center-to-center pixel spacing. Operation is simplified by internal logic that requires only a serial input SI1 through SI5 for each section and a common clock for the five sections.
