Ams recommends a PCB layout with a solid ground plane underneath the sensor, and a small keep-out area around the sensor to minimize noise and interference.
The TSL13S-LF outputs a 16-bit digital signal that represents the ambient light level. Ams provides a recommended algorithm for calculating lux values in the application note AN4991, which involves scaling the output data and applying a non-linear correction factor.
The recommended operating voltage range for the TSL13S-LF is 2.5V to 3.6V. Operating the sensor outside of this range may affect its accuracy and linearity, and may also reduce its sensitivity to low light levels.
The TSL13S-LF has a built-in IR filter that reduces the sensor's sensitivity to IR light. However, it is not completely immune to IR interference. In applications with high IR content, additional filtering or shielding may be necessary to ensure accurate ambient light measurements.
Ams recommends calibrating the TSL13S-LF during the manufacturing process, and recalibration is typically not necessary during the sensor's lifetime. However, if the sensor is used in an application with extreme environmental conditions or is subject to physical stress, recalibration may be necessary to ensure accurate performance.
