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 communication is accomplished 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.
