【產品簡介】
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 device has been temperature-compensated for the ultraviolet-to-visible light range of 320 nm to 700 nm and responds over the light range of 320 nm to 1050 nm (Note that the TSL235R/TSL237R differ only in their output frequency range).
【產品特色】
- Communicates directly with a microcontroller.
- Single-supply operation.
- Compact 3-lead clear plastic package.
- High-resolution conversion of light intensity to frequency with no external components.
【產品規格】
- Nonlinearity Error (Typically 0.2% at 100 kHz).
- Stable 150 ppm/°C Temperature Coefficient.
- Supply Voltage: 2.7 - 5.5 VDC.
- Operating Temperature range: -25 - 70 °C.
- Typical current draw: 2 mA.
- Output Frequency: 40 - 60 kHz.
