Layout Considerations
The ISL29013 is relatively insensitive to layout. Like other
I
even in significantly noisy environments. There are only a
few considerations that will ensure best performance.
Route the supply and I
sources of noise. Use two power-supply decoupling
capacitors, 4.7µF and 0.1µF, placed close to the device.

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.
