ISL29028AIROZ-T7 - Renesas Electronics

Description: The ISL29028A is an integrated ambient and infrared light-to-digital converter with a built-in IR LED driver and I2C interface (SMBus compatible). This device uses two independent ADCs for concurrently measuring ambient light and proximity in parallel. The flexible interrupt scheme is designed for minimal microcontroller utilization. For ambient light sensor (ALS) data conversions, an ADC converts photodiode current (with a light sensitivity range up to 2000 Lux) in 100ms per sample. The ADC rejects 50Hz/60

ISL29028AIROZ-T7 Frequently Asked Questions (FAQs)

  • The recommended PCB layout for the ISL29028AIROZ-T7 involves placing the sensor near the top of the PCB, away from other components, and using a ground plane to minimize noise. A dedicated analog ground plane is also recommended to reduce noise and improve accuracy.
  • Calibration of the ISL29028AIROZ-T7 involves adjusting the gain and offset registers to match the specific application requirements. This can be done using the device's built-in calibration registers or through external calibration using a microcontroller or other external device.
  • The recommended power-on sequence for the ISL29028AIROZ-T7 involves applying VDD first, followed by VLOGIC, and then enabling the device by setting the EN pin high. This ensures proper device startup and minimizes the risk of latch-up or other issues.
  • The ISL29028AIROZ-T7 generates interrupts when the ambient light level exceeds a certain threshold. To handle these interrupts, the microcontroller should be configured to detect the interrupt signal and execute the corresponding interrupt service routine to read the light data and clear the interrupt flag.
  • The ISL29028AIROZ-T7 can measure ambient light levels up to 128,000 lux, making it suitable for a wide range of applications, from low-light indoor environments to bright outdoor conditions.
