Product Description
The AMIS-74980x is a wide dynamic range light sensor
with an analog or digital output. There are several
versions of the analog output; one with 1uA current
output at 1000lux all the way to 1mA at 1000lux. The
digital output version has a built-in 16-bit ADC with a 2-
Application Information
The AMIS-74980x is primarily used in ambient light

where adjustments are made to display brightness or
contrast based on the brightness of the ambient light, as
perceived by the human eye. Conventional SI detectors

wire SMBus or I2C digital interface. The sensor employs
AMI Semiconductor's proprietary CMOS image sensing
technology which provides low noise and high dynamic
range output signals and a light response similar to the
response of the human eye.
respond too strongly to infrared light - a large
component of incandescent lighting - preventing natural
human eye response. The AMIS-74980x effectively filters
infrared light through proprietary techniques providing
human eye response.
