ISL29102IROZ-T7A - Renesas Electronics

Description: The ISL29102 is a low cost, light-to-voltage silicon optical sensor combining a photodiode array, a nonlinear current amplifier, and a micro-power op amp on a single monolithic IC. Similar to human eyes, the photodiode array has peak sensitivity at 550nm and spans from 400nm to 600nm, rejecting UV light and IR light. The input luminance range is from 0.3 lux to 10,000 lux. The integrated nonlinear current amplifier boosts and converts the photodiode signal in a square root fashion, extending the light input

ISL29102IROZ-T7A Frequently Asked Questions (FAQs)

  • A good PCB layout for the ISL29102IROZ-T7A involves keeping the sensor and its associated components away from high-current carrying traces, using a solid ground plane, and minimizing the length of the traces connecting the sensor to the microcontroller. Additionally, it's recommended to use a separate analog ground plane for the sensor and its associated components.
  • Calibration of the ISL29102IROZ-T7A involves adjusting the gain and offset of the sensor to match the specific application's requirements. This can be done by taking readings at different light levels and adjusting the gain and offset registers accordingly. It's also recommended to perform a dark calibration to account for any offset errors.
  • The ISL29102IROZ-T7A is rated for operation from -40°C to 85°C, but it's recommended to operate the device within a temperature range of 0°C to 70°C for optimal performance and accuracy.
  • Yes, the ISL29102IROZ-T7A can be used with a microcontroller that has a 5V supply voltage, but it's recommended to use a level shifter or voltage divider to ensure that the sensor's output voltage does not exceed the microcontroller's input voltage rating.
  • The ISL29102IROZ-T7A outputs 16-bit data that represents the lux reading. To get accurate lux readings, the output data needs to be scaled and compensated for temperature and other environmental factors. The datasheet provides a formula for calculating the lux reading from the output data, and it's recommended to use this formula or a similar approach to get accurate readings.
