The pixels are on 85-µm centers and measure 85 µm (H) by 77 µm (W) with 8 µm between pixels. Associated with each pixel is a charge integrator/amplifier and sample-hold circuit. All pixels have concurrent integration periods and sampling times. Data communication is accomplished through a three-wire serial interface. The array is split into three 34-pixel zones, with each zone having programmable gain and offset levels. The TSL2301 is intended for use in high-performance, cost-critical imaging and optical sensing applications. www.DataSheet4U.com Functional Block Diagram PIXEL ARRAY WITH INTEGRATORS AND S-H PIXCLK SI HOLD ZERO LEFT EVEN RIGHT ODD RIGHT EVEN IREF 8 SCLK SDIN SDOUT DIGITAL I/O AND CONTROL 5 DB<7:0> ADDR<4:0> READ WRITE OUTPUT CHARGE-TOVOLTAGE CONVERTER WITH PROGRAMMABLE GAINS AND OFFSETS VREF IREF BIAS BLOCK 3 SECTOR RESET/SAMPLE START ADCLK DUAL 8-BIT SA ADC VREF IREF ...
