Surface-mount Package OPICTM Logarithmic Output Ambient Light Sensor
Description
The GA1A1S201WP is an surface-mount ambient light sensor with a spectral response similar to that of the human eye. This response curve means the sensor is highly accurate when used as the basis of an ambient light sensor, or camera exposure sensor. The integrated photodiode and amplifier circuit makes the GA1A1S201WP ideal for use in space-constrained applications, or for anywhere a sensor may be wanted but wasted space is not.

Manufacturing Guidelines Storage and Handling
1. Store these parts between 5C and 30C, at a relative humidity of less than 70%. 2. After breaking the package seal, maintain the environment within 5C to 25C, at a relative humidity of less than 60%, and mount the parts within three days. 3. When storing the parts after breaking the seal, Sharp recommends storage of no longer than two weeks in a dry box or by resealing the parts in a moisture-proof bag with a desiccant. 4. Do not bake these parts unless the humidity indicator within the package changes color or if the handling guidelines given above could not be followed. Bake these parts only once, and while the parts are still in tape-andreel. Suspend the reels by the spindle in the oven, instead of laying the reels flat. Bake the reels at 65C for 48 hours. Less preferable is to bake the parts either temporarily mounted or on a metal tray at 125C, for 16 to 24 hours.
Soldering Information
1. When using solder reflow methods, follow the time and temperature profile shown in Figure 1. Sharp recommends sending parts through this process two times or less. 2. If using an infrared lamp to preheat the parts, such heat sources may cause localized high temperatures in the part's resin. Be sure to keep the heat profile within the guidelines shown. 3. Do not subject the package to excessive mechanical force during soldering as it may cause deformation or defects in plated connections. Internal connections may be severed due to mechanical force placed on the package due to the PCB flexing during the soldering process. 4. Sharp recommends checking the soldering process to ensure these guidelines are followed.

Cleaning Instructions
1. Confirm this device's resistance to process chemicals before use, as certain process chemicals may affect the optical characteristics. 2. Solvent cleaning: Solvent temperature should be 45C or below. Immersion time should be 3 minutes or less. 3. Ultrasonic cleaning: The effect upon devices varies due to cleaning bath size, ultrasonic power output, cleaning time, PCB size and device mounting circumstances. Sharp recommends testing using actual production conditions to confirm the harmlessness of the ultrasonic cleaning methods. 4. Recommended solvent materials: Ethyl alcohol, Methyl alcohol, and Isopropyl alcohol.
