Selected Device: TSL237SM-LF Features
The TSL237 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 TSL237 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 3-lead clear plastic side-looker package with an integral lens
- High-Resolution Conversion of Light Intensity to Frequency With No External Components
- Communicates Directly With a Microcontroller
- High Irradiance Responsivity (2.3 kHz/(uW/cm²) at 524 nm)
- Low Dark Frequency (<2 Hz at 50° C)
- Single-Supply Operation (2.7V to 5.5V)
- Stable 200 ppm/°C Temperature Coefficient
- RoHS Compliant (-LF Package Only)
