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-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.

NOTES:
2. DSNU is the difference between the highest value pixel and the lowest value pixel of the device under test when the array is not
illuminated.
3. PRNU does not include DSNU.
4. PRNU is the difference between the highest value pixel and the lowest value pixel of the device under test when the array is uniformly
illuminated at nominal white level (typical average output level = 200).
