Suggested PCB Footprint

It is important that the users check the “Surface Mount

Assembly Guidelines for Optical Dual FlatPack No Lead

(ODFN) Package” before starting ODFN product board

mounting.

Layout Considerations

The ISL29010 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. Use two power-supply decoupling

capacitors, 4.7µF and 0.1µF, placed close to the device.

Typical Circuit

A typical application for the ISL29010 is shown in Figure 6.

The ISL29010’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.
