isl29003 Intersil Corporation, isl29003 Datasheet - Page 12

• Manufacturer Part Number: isl29003
• Description: Light-to-digital Output Sensor With High Sensitivity, Gain Selection, Interrupt Function And I2c Interface
• Manufacturer: Intersil Corporation

Suggested PCB Footprint
Footprint pads should be a nominal 1-to-1 correspondence
with package pads. The large, exposed central die-mounting
paddle in the center of the package requires neither thermal
nor electrical connection to the PCB, and such connection
should be avoided.
Layout Considerations
The ISL29003 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.
