9 / 12 page 9 FN6732.0 March 3, 2009 Typical Circuit A typical application for the ISL29021 is shown in Figure 4. The ISL29021’s I2C address is internally hardwired as 1000100. 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. FIGURE 3.
