The EAALST03RDAA0 is an ambient light and infrared (IR) module sensor designed for use in mobile radio frequency (RF) communication devices and other consumer electronics to detect and measure the ambient light and IR radiation of a given area, providing useful readings for many applications. It is part of Opto’s family of Optical Sensors – Ambient Light, IR, UV Sensors.

The EAALST03RDAA0 has a measuring range of 0.25 lux to 2048 lux for visible light and 65 nW/cm2 to 128 mW/cm2 for IR radiation. It is equipped with a built-in IR cutoff filter on the photocell input for better ambient light accuracy and resolution. It also has a programmable analog gain of up to 16x. This allows for accurate readings even in bright ambient light. The smart analog-to-digital converter (ADC) has low noise and negligible offset. It also has a wide operating voltage range between 2.7V and 5.5V which makes it suitable for a wide variety of applications.

The EAALST03RDAA0 works on a principle of active thread sensing. This means that the sensor collects light emitted or reflected from a particular area or object and the data is converted into electrical signals for analysis. The on-chip photocell senses the ambient light and infrared radiation and its associated circuitry converts these readings into digital data. This digital data can then be sent to MCUs and other receiving units for further analysis and processing.

The EAALST03RDAA0 is an ideal solution for applications that require accurate and reliable ambient light and infrared radiation sensing. It can be used in mobile radio frequency communication devices, such as RFID readers, to accurately detect and measure the amount of light emitted or reflected by an object. It is also suitable for consumer electronics applications such as automatic lighting brightness control, remote control operation, and digital signage displays.

The EAALST03RDAA0 is a robust and reliable ambient light and infrared (IR) module sensor that is designed to provide highly accurate and consistent measurements in a variety of ambient light and IR radiation applications. With its programmable analog gain of up to 16x, low noise, and wide operating voltage range, the EAALST03RDAA0 is an excellent choice for many light and IR sensing applications.
