... Single 5-V Supply Description The TSL2301 is a 300-dpi, 102-pixel linear optical sensor array with an integrated 8-bit analog-to-digital converter. The pixels are on 85- m centers and measure (W) with 8 m between pixels. Associated with each pixel is a charge integrator/amplifier and sample-hold circuit. All pixels have concurrent integration periods and sampling times ...

... Register address map The TSL2301 contains seven registers (Table 2). Three registers control the gain of the analog-to-digital converters (ADCs). Three other registers allow the offset of the system to be corrected. Together the gain and offset registers are used to maximize the achievable dynamic range. The last register is a mode register that selects both device cascade options and production test options ...

... SDOUT Command description The TSL2301 is a slave device that reacts strictly to commands received from the controller. There are three types of commands, reset commands, pixel action commands and register commands. These commands cause the device to perform functions such as: reset, integrate, sample, etc. Each command is described in more detail in Table 3 ...

... RESET puts the pixel integrators into the auto-zero/reset state. Any values that were being held in the array’s sample/hold circuits are lost. On power up of the TSL2301 necessary to hold SDIN high for 30 clocks before initiating a reset command. In addition, to fully reset the device recommended that 3 consecutive RESET commands be issued as part of the power up routine ...
