11 / 16 page ISL29028A 11 FN7721.2 March 24, 2011 Typical Circuit A typical application for the ISL29028A is shown in Figure 5. The ISL29028A’s I2C address is internally hardwired as 0b100010<x>, with x representing the logic state of input I2C address pin ADDR0. The device can be tied onto a system’s I2C bus together with other I2C compliant devices. Soldering Considerations Convection heating is recommended for reflow soldering; direct- infrared heating is not recommended. The plastic ODFN package does not require a custom reflow soldering profile, and is qualified to +260°C. A standard reflow soldering profile with a +260°C maximum is recommended. Suggested PCB Footprint It is important that users check the “Surface Mount Assembly Guidelines for Optical Dual FlatPack No Lead (ODFN) Package” before starting ODFN product board mounting. (http://www.intersil.com/data/tb/TB477.pdf) Layout Considerations The ISL29028A is relatively insensitive to layout. Like other I2C devices, it is intended to provide excellent performance even in significantly noisy environments. There are only a few considerations that will ensure best performance. Route the supply and I2C traces as far as possible from all sources of noise. A 0.1µF and 1µF power supply decoupling capacitors need to be placed close to the device. ALS Sensor Window Layout Special care should be taken to ensure that the sensor, as outlined in the sensor location outline, is uniformly illuminated. Shadows that result from off angle window openings that affect that uniform illumination can affect the measurement results.
