V to 9 V Low Supply Current µa Typical at V DD = 5 V Advanced LinCMOS Technology description The TSL50, TSL5, and TSL5 are light-to-voltage optical sensors, each combining a photodiode and a transimpedance amplifier (feedback resistor = 6 MΩ, 8 MΩ, and MΩ respectively) on a single monolithic IC. The output voltage is directly proportional to the light intensity (irradiance) on the photodiode. These devices utilize Texas Instruments silicon-gate LinCMOS technology, which provides improved amplifier offset-voltage stability and low power consumption. functional block diagram + Voltage Output absolute maximum ratings over operating free-air temperature range (unless otherwise noted) Supply voltage, V DD (see Note ) V Output current, I O ±0 ma Duration of short-circuit current at (or below) 5 C (see Note ) s Operating free-air temperature range, T A C to 85 C Storage temperature range, T stg C to 85 C Lead temperature,6 mm (/6 inch) from case for 0 seconds C Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device.
