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 m (H) by 77 m (W) and spaced on 85 m 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.
