ZOPT2201

Digital Ambient Light and UVB Energy Sensor ZOPT2201 Datasheet Brief Description The ZOPT2201 Sensor integrates an ambient light sensor (ALS) and ultraviolet energy sensor (UVBS). The device can be connected via an I²C interface to an external microcontroller. Other I²C or SMBus devices can be connected to the same interface. The device has a programmable interrupt with hysteresis to respond to events and reduce the microcontroller tasks. A major application of the device is in smart phones or other mobile devices to enable brightness control of display panels (ALS) and diverse health care applications or contextual awareness algorithms (UVBS). Features  High ambient light and UVB energy sensitivity  Superior infrared energy suppression  Very stable spectral response over angle of light incidence  Wide dynamic range  Excellent temperature compensation  Lowest conversion repeat noise  I²C interface capable of standard mode (100kHz) or fast mode (400kHz) communi...
