Device Operational Details The voltage developed at the output pin (OUT) is given by: (EQ1) V O = V D + (Re) (Ee) where: • V O is the output voltage • V D is the output voltage for dark condition (E e = 0) • R e is the device responsivity for a given wavelength of light given in mV/(μW/cm2) • E e is the incident irradiance in μW/cm2 V D is a fixed offset voltage resulting primarily from the input offset voltage of the internal op amp. As shown in the equation above, this voltage represents a constant, light-independent term in the total output voltage VO. At low light levels, this offset voltage can be a significant percentage of V O. For optimum performance of any given device over the full output range, the value of V D should be measured (in the absence of light) and later subtracted from all subsequent light measurements (see Figure 10 and Figure 11). ams Datasheet [v1-00] 2016-Jun-07 Page 13 Document Feedback TSL250RD, TSL251RD, TSL260RD, TSL261RD − Application Information PCB Pad Layout Suggested PCB pad layout guidelines for the D package is shown in Figure 17.

To prevent these adverse conditions, all devices shipped in carrier tape have been pre-baked and shipped in a sealed moisture-barrier bag. No further action is necessary if these devices are processed through solder reflow within 24 hours of the seal being broken on the moisture-barrier bag. However, for all devices shipped in tubes or if the seal on the moisture barrier bag has been broken for 24 hours or longer, it is recommended that the following procedures be used to ensure the package molding compound contains the smallest amount of absorbed moisture possible. For Devices Shipped in Tubes: 1. Remove devices from tubes 2. Bake devices for 4 hours, at 90°C 3. After cooling, load devices back into tubes 4. Perform solder reflow within 24 hours after bake Bake only a quantity of devices that can be processed through solder reflow in 24 hours. Devices can be re-baked for 4 hours, at 90°C for a cumulative total of 12 hours (3 bakes for 4 hours at 90°C). For Devices Shipped in Carrier Tape: 1. Bake devices for 4 hours, at 90°C in the tape 2. Perform solder reflow within 24 hours after bake Bake only a quantity of devices that can be processed through solder reflow in 24 hours. Devices can be re−baked for 4 hours in tape, at 90°C for a cumulative total of 12 hours (3 bakes for 4 hours at 90°C).
