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.

Light-to-Voltage Optical Sensor - The TSL253R is a precision CMOS Light-to-Voltage sensor that combines a photodiode and a transimpedance amplifier on a single monolithic IC. The feedback resistor is 16 Megohm. The output voltage is directly proportional to the light intensity on the photodiode. At 635nm, the irradiance responsivity is 137 mV/(uW/cm2) with an output rise and fall time of 7usec.
Programmable Light-to-Frequency Converters - The TSL230R-LF, TSL230AR-LF and TSL230BR-LF programmable light-to-frequency converters combine a configurable silicon photodiode and a current-to-frequency converter on single monolithic CMOS integrated circuits. All inputs and the output are TTL compatible, allowing direct two-way communication with a microcontroller for programming and output interface. An output enable (OE) is provided that places the output in the high-impedance state for multiple-unit sharing of a microcontroller input line. .
