The News:
The Optoelectronics group of Vishay Intertechnology introduces a new high-accuracy digital ambient
light sensor for flat-panel televisions and consumer handheld devices. The Vishay Semiconductors
VEML7700 combines a photo-diode, low-noise amplifier, and 16-bit ADC in a miniature, transparent
surface-mount package measuring 6.8 mm by 3.0 mm by 2.35 mm. The sensor adopts Filtron
technology and supports an I²C bus interface for simple operation.
 Compact size saves space
 Side- or top-view device provides mounting and placement flexibility
 Side-view package offers the same dimensions and optical axis height as Vishay’s TSOP772 IR
receiver
 Greatly simplifies window designs
 Filtron technology enables ambient light spectral sensitivity close to that of the human eye
 O-Trim™ technology provides output tolerance of ≤ 10 %
 Allows for operation in applications with low-transmittance (dark) lens designs
