TSL250R, TSL251R, TSL252R LIGHT-TO-VOLTAGE OPTICAL SENSORS TAOS028G JUNE 2007 PACKAGE S PACKAGE SM Monolithic Silicon IC Containing SIDELOOKER SURFACE MOUNT Photodiode, Operational Amplifier, and (FRONT VIEW) SIDELOOKER Feedback Components (FRONT VIEW) Converts Light Intensity to a Voltage High Irradiance Responsivity, Typically 2 137 mV/( W/cm ) at = 635 nm (TSL250R) p Compact 3-Lead Clear Plastic Package Single Voltage Supply Operation Low Dark (Offset) Voltage....10 mV Max Low Supply Current......1.1 mA Typical Wide Supply-Voltage Range.... 2.7 V to 5.5 V Replacements for TSL250, TSL251, and 1 2 3 TSL252 GND V OUT DD RoHS Compliant (LF Package Only) 1 2 3 GND V OUT DD Description The TSL250R, TSL251R, and TSL252R are light-to-voltage optical sensors, each combining a photodiode and a transimpedance amplifier (feedback resistor = 16 M, 8 M, and 2.8 M 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. When supplied in the lead (Pb) free package, the device is RoHS compliant.
