Product Specification
| Description | SMD-4P Ambient Light, IR, UV Sensors RoHS | Mfr. Part # | TSL237T |
| Package | SMD-4P | Model Number | TSL237T |
The TSL237 is a high-sensitivity light-to-frequency converter that integrates a silicon photodiode and a current-to-frequency converter on a single CMOS IC. It outputs a square wave with a frequency directly proportional to light intensity, enabling direct interface with microcontrollers. Features include single-supply operation, stable temperature compensation, a wide input dynamic range, and low dark frequency, making it suitable for applications requiring precise light level detection and measurement across the ultraviolet-to-visible spectrum.
