Description
The TSL3301CL is a high-sensitivity 300-dpi, linear optical sensor array with integrated 8-bit analog-to-digital
converters. The array consists of 102 pixels: 100 inner pixels and 2 end pixels. The inner pixels measure 85 糾
(H) by 77 糾 (W) on 85-糾 centers and the end pixels are 132 糾 (H) by 49 糾 (W). 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 TSL3301CL 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.
