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

μm

(H) by 77

μm (W) on 85-μm centers and the end pixels are 132 μm (H) by 49 μm (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.
