Light-to-Voltage Optical Sensors - The TSL250R, TSL251R and TSL252R are light-to-voltage optical sensors, each combining a photodiode and a transimpedance amplifier (feedback resistor = 16 Megohm, 8 Megohm and 2.8 Megohm, respectively) on a single monolithic IC. Output voltage is directly proportional to the light intensity (irradiance) on the photodiode. These devices have improved amplifier offset-voltage stability and low power consumption and are supplied in a 3-lead clear plastic sidelooker package with an integral lens.

Output voltage is directly proportional to the light intensity (irradiance) on the photodiode. These devices have improved amplifier offset-voltage stability and low power consumption and are supplied in a 3-lead plastic sidelooker package with an integral visible light cutoff filter and lens.
High-Sensitivity Light-to-Frequency Converter - The TSL238D, TSL238T light-to--frequency converters combine 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. Both devices have been temperature compensated for the ultraviolet-to-visible range of 320 nm to 700 nm and respond over the light range of 320 nm to 1050 nm. The TSL238D is characterized for operation over the temperature range of -25 degrees C to 70 degrees C. The TSL238T is characterized for operation over the temperature of -40 degrees C to 85 degrees C.
