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 reference voltage circuit are built in.
• Small-sized transparent molded plastic package.

APPLICATION
   Automatic exposure control for cameras,illuminometers.
