1 / 10 page TSL220 LIGHT-TO-FREQUENCY CONVERTER SOES003 – AUGUST 1990 – REVISED JUNE 1991 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D High-Resolution Conversion of Light Intensity to Frequency D Wide Dynamic Range...118 dB D Variable (and Single) Supply Range...5 V to 10 V D High Linearity...Typically Within 2% of FSR (C = 100 pF) D High Sensitivity... Can Detect Change of 0.01% of FSR D CMOS Compatible Output for Digital Processing D Minimum External Components D Microprocessor Compatible description The TSL220 consists of a large-area photodiode and a current-to-frequency converter. The output voltage is a pulse train and its frequency is directly proportional to the light intensity (irradiance) on the photodiode. The output is CMOS† compatible and its frequency may be measured using pulse counting, period timing, or integration techniques. The TSL220 is ideal for light-sensing applications requiring wide dynamic range, high sensitivity, and high noise immunity. The output frequency range is determined by an external capacitor; hence, the desired output frequency is adjustable for a given light intensity at the input. The TSL220 is characterized for operation over the temperature range of – 25 °C to 70°C. mechanical data The photodiode and current-to-frequency converter are packaged in a clear plastic 8-pin dual-in-line package. The active chip area is typically 4,13 mm2 (0.0064 in2).
