2-CHANNEL SPD SENSOR BUILT-IN DETECT AMOUNT OF LIGHT
1
DESCRIPTION
The M52979F is a semiconductor integrated circuit designed to
detect quantity of light and used for cameras and illuminometers.
Because a high-sensitivity SPD sensor is built in this IC, it is
possible not only to reduce the space and expenses to mount it but
also to conduct wide-ranging detection of light volume.
FEATURES
A 2-channel SPD sensor is built in.(1-channel for spot and one
for average)
Wide-ranging detection of light volume.
A temperature sensor circuit and a temperature constant refer-
ence voltage circuit are built in.
Small-sized transparent molded plastic package.
APPLICATION
Automatic exposure control for cameras,illuminometers.
RECOMMENDED OPERATING CONDITION
Supply voltage range........................................................2.8 to 6.5V
Rated supply voltage................................................................4.65V
Light input range............................................SPOT 1 to 100000 lux
AVE. 0.1 to 14400 lux
