AMS104W

The AMS104W is a digital ambient light sensor with integrated rectangular field of view designed for a variety of applications. This type of optical sensor is used to measure ambient light levels and helps to detect small changes in light intensity. It is designed to offer precise operating and high sensitivity levels with the aid of an enhanced operational amplifier.

The AMS104W consists of a photo sensor and transimpedance preamplifier. The preamplifier is integrated to directly interface with a low power microcontroller by adjusting the gain so that the travel of the output voltage is between 0V and VCC. A high performance blue sensitive photo sensor is used. Additionally, the device has a wide linear range 4.9 lux to 22.3K lux for ambient light sensing. With fast start-up time, low offset voltage and low power dissipation, the AMS104W is one of the best performance photocell devices in the market.

The main application areas of the AMS104W include energy-saving lighting, digital displays, instrument panels, data processing systems, portable systems, diagnostic medical systems, consumer products lighting, interactive products lighting and time-of-flight systems. The device operates with a variety of light visible to the human eye as well as in the infrared and ultraviolet ranges.

The operating principle or the functionality of AMS104W is based on measuring incident light. The device works on a linear principle of a photoelectric sensor. It allows light to reach a photodiode which is converted into an electric current. This electric current is then amplified by the integrated transimpedance amplifier. The output of the device is between 0V and VCC. The gain adjustment allows the output to travel between these two limits. The light sensitivity is programmed by making some changes in the external components of the device.

In summary, the AMS104W is a versatile and reliable optical sensor which can be used in a variety of applications. It is designed to offer high sensitivity and precision in response to different light conditions, ranging from visible light to infrared and ultraviolet facing the challenge of reducing the power consumption.
