AS7024
Biosensors
General Description
The AS7024 device provides a flexible analog front end for light
sensing applications. The photodiode input circuit can be
configured in different ways to guarantee best tradeoff
between speed and sensitivity for a large number of different
sensing applications.
AS7024 is targeted for wearables (fitness band, smart watch).
