6 / 97 page  8 A bright illuminated white target right in front of the chip with lens leads to an IVBS of approx. 3.8 mA. At room temperature, IVBS is approx. 3.6 mA without any illumination. IVBS with strong illumination (approx. 55 mW/cm2, no lens) typ. 17 mA. 1.2. Absolute maximum ratings Parameter Conditions Supply voltage VDD, VDDPLL -0.5V ... +2.0V Supply voltage VDDIO, VDDA, VDDLED -0.5V ... +5.5V Supply voltage VDDPXH -0.5V ... +13.5V Supply voltage VBS -12.0 ... +0.5V Voltage to any pin in the same VSC supply class. For Supply Classes refer to Table 1: Operating conditions and electrical characteristics. For Supply Classes vs. pin correspondence refer Table 8: Pin list. VSC min - 0.3V … VSC max + 0.3V ESD rating Note: This is a highly sensitive CMOS mixed signal device. Handling and assembly of this de- vice should only be done at ESD protected workstations.
