(11) Simultaneous exposure of the DMD to the maximum Recommended Operating Conditions for temperature and UV illumination will

reduce device lifetime.

(12) The array temperature cannot be measured directly and must be computed analytically from the temperature measured at test point 1

(TP1) shown in Figure 18 and the Package Thermal Resistance using Micromirror Array Temperature Calculation.

(13) Per Figure 1, the maximum operational array temperature should be derated based on the micromirror landed duty cycle that the DMD

experiences in the end application. Refer to Micromirror Landed-On/Landed-Off Duty Cycle for a definition of micromirror landed duty

cycle.

(14) Array temperatures beyond those specified as long-term are recommended for short-term conditions only (power-up). Short-term is

defined as cumulative time over the usable life of the device and is less than 500 hours for temperatures between long-term maximum

and 75°C, less than 500 hours for temperatures between 0°C and -10°C, and less than 25 hours for temperatures between -10°C and -

20°C.

(15) Temperature delta is the highest difference between the ceramic test point 1 (TP1) and anywhere on the window edge shown in

Figure 18. The window test points TP2 and TP3 shown in Figure 18 are intended to result in the worst case delta temperature. If a

particular application causes another point on the window edge to result in a larger delta temperature, that point should be used.

(16) Window temperature is the highest temperature on the window edge shown in Figure 18. The locations of thermal test points TP2 and

TP3 in Figure 18 are intended to measure the highest window edge temperature. If a particular application causes another point on the

window edge to result in a larger delta temperature, that point should be used.

(17) Long-term is defined as the usable life of the device.

(18) Dew points beyond the specified long-term dew point are for short-term conditions only, where short-term is defined as less than 60

cumulative days over the usable life of the device (operating or storage).
