Ambient light sensor with voltage output
The ADPD2211ACPZ-R7 is an ambient light sensor from Analog Devices, part of the ADPD2211 family, with a peak spectral sensitivity at 528 nm — the green region where the human eye's photopic response peaks, making it suitable for display backlight control and daylight sensing in consumer and industrial panels. It outputs an analog voltage proportional to the incident light level, operating from a single 1.8 V supply rail. The low supply voltage keeps power dissipation minimal in battery-powered or energy-harvesting designs.
Package and board-fit considerations
The small outline suits space-constrained sensor modules or edge-mounted boards. The 1.8 V supply rail is common in low-voltage mixed-signal chains, so no additional regulator is needed if the system already runs at that voltage.
