Selected Device: TSL238D Features
The TSL238D light-to-frequency converter combines a silicon photodiode and a current-to-frequency converter on a single monolithic CMOS integrated circuit. The output is a square wave (50% duty cycle) with frequency directly proportional to light intensity. Because it is TTL compatible, the output allows direct interface to a microcontroller or other logic circuitry. The TSL238 has been temperature compensated for the ultraviolet-to-visible range of 320 nm to 700 nm and responds over the light range of 320 nm to 1050 nm. The device is characterized for operation over the temperature range of -25 degrees C to 70 degrees C and supplied in a compact 4-lead surface package. The device is RoHS compliant.
- High-Resolution Conversion of Light Intensity to Frequency With No External Components
