ISL29038IROZ-T7 - Renesas Electronics

Description: The ISL29038 is a low power ambient light sensor (ALS) and proximity (PROX) sensor. It has a built-in IR-LED driver for proximity function. The ALS function measures the amount of light (in the visible spectrum) incident on the ISL29038. The ALS function has a programmable ambient IR-rejection, which allows fine tuning of light source variations and is ideal for light sensor applications under dark protective glass. The ALS provides a 12-bit measurement. A passive optical filter removes unwanted wavelengths

ISL29038IROZ-T7 Frequently Asked Questions (FAQs)

  • A good PCB layout for the ISL29038IROZ-T7 involves keeping the sensor away from other components that may interfere with its light sensing capabilities. A minimum clearance of 1 mm around the sensor is recommended. Additionally, the sensor should be placed on the top layer of the PCB to minimize interference from other components.
  • Calibration of the ISL29038IROZ-T7 involves adjusting the internal gain and offset registers to match the specific application's requirements. This can be done by taking readings in a known light source and adjusting the registers accordingly. Renesas provides a calibration guide and software tools to assist with this process.
  • The recommended power-on sequence for the ISL29038IROZ-T7 is to first apply VDD, then apply VLOGIC, and finally apply the clock signal. This ensures that the internal voltage regulators and analog circuits are properly initialized.
  • The ISL29038IROZ-T7 outputs 16-bit data that represents the ambient light level. To get accurate lux readings, the output data needs to be scaled and compensated for temperature effects. Renesas provides a formula and coefficients to convert the output data to lux values.
  • The ISL29038IROZ-T7 is specified to operate from -40°C to 85°C. However, the sensor's accuracy and sensitivity may degrade at extreme temperatures. It is recommended to operate the sensor within a temperature range of 0°C to 60°C for optimal performance.
