ams provides a recommended PCB layout in their application note AN5015, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
The interrupt output of the TSL25713FN is an open-drain output, which means it requires an external pull-up resistor to VCC. The interrupt is triggered when the ambient light level exceeds a programmable threshold, and it remains active until the threshold is cleared or the device is reset.
The TSL25713FN's accuracy is affected by temperature, with a typical temperature coefficient of -0.2% per °C. This means that the sensor's output will decrease by 0.2% for every degree Celsius increase in temperature. However, this effect can be compensated for in software using temperature calibration data provided by ams.
Yes, the TSL25713FN is designed to be immune to EMI and has been tested to meet the requirements of IEC 61000-4-3 (Radiated Immunity) and IEC 61000-4-6 (Conducted Immunity). However, it's still important to follow proper PCB design and layout practices to minimize the effects of EMI on the sensor's performance.
The TSL25713FN outputs a 16-bit digital value that represents the ambient light level. To convert this value to lux, you need to use the sensor's sensitivity and gain settings, as well as the integration time. ams provides a formula and example code in their application note AN5002 to help with this calculation.
