TSL3301 Datasheet | TAOS

Description The TSL3301 is a high-sensitivity 300-dpi, linear optical sensor array with integrated 8-bit analog-to-digital converters. The array consists of 102 pixels, each measuring 85 µm (H) by 77 µm (W) and spaced on 85 µm centers. Associated with each pixel is a charge integrator/amplifier and sample-hold circuit. All pixels have concurrent integration periods and sampling times. The array is split into three 34-pixel zones, with each zone having programmable gain and offset levels. Data munication is acplished through a three-wire serial interface. Intended for use in high performance, cost-sensitive scanner applications, the TSL3301 is based on a linear sensor array die that has expanded capability, including multi-die addressing and cascade options. Please contact TAOS for additional information on die and multi-die package availability.
