ISL29006IROZ-EVALZ開發(fā)板套件編程器的評估板-傳感器規(guī)格書PDF中文資料

The ISL29006, ISL29007, and ISL29008 are light-to-current

silicon optical sensors combining a photodiode array and a

current amplifier on a single monolithic IC. The photodiode’s

spectral sensitivity approximates the human eye response

peaking at 550nm with virtually no infrared (IR) response.

Exposed to light, these light sensors give current outputs

that are linearly proportional to the light intensity. The output

of ISL29006 is configured as a current source, and the

output of ISL29007 is configured as a current sink. Both

ISL29006 and ISL29007 offer an EN pin that can be used for

a polling scheme to extend the battery life of portable

devices.

The ISL29008 has dual outputs simultaneously sinking and

sourcing current. With output currents at opposite polarity, it

can simultaneously control two light sources/drivers that

have incongruent illumination requirement depending on

ambient light conditions. For example, at bright ambient light

levels, display backpanels need more intensity while the

keyboard illumination needs to be dimmer, whereas at

darker ambient light levels, display backpanels need less

intensity while the keyboard illumination needs to be

brighter.

By connecting an external resistor from ISRC to GND or

from ISNK to VDD, the current output can be converted into

voltage output.

Housed in an ultra-compact 2mmx2.1mm ODFN clear

plastic package, this device is excellent for power saving

control function in cell phones, PDAs and other handheld

applications.
