Small, Low Power, Current-Output Ambient Light Photo Detect IC

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.

Features

• 0.5 lux to 10,000 lux range

• 1.8V to 3.6V supply range

• Low supply current (3.5µA @ 100 lux)

• Fast response time

• Close to human eye response

• IR Rejection

• Internal dark current compensation

• Lux to current source or/and sink

• Excellent output linearity of luminance

• 6 Ld ODFN: 2mmx2.1mmx0.7mm

• Pb-free (RoHS compliant)

Applications

• Display and keypad dimming for:

- Mobile devices: smart phone, PDA, GPS

- Computing devices: notebook PC, webpod

- Consumer devices: LCD-TV, digital picture frame, digital camera

• Industrial and medical light sensing
