(1) All voltage values are with respect to GND (VSS). VOFFSET, VCC, VBIAS, VRESET, and VSS power supplies are required for the normal DMD operating mode.
(2) To prevent excess current, the supply voltage delta |VBIAS – VOFFSET| must be less than 8.75 V.
(3) Simultaneous exposure of the DMD to the maximum Recommended Operating Conditions for temperature and UV illumination reduces device lifetime.
(4) The array temperature cannot be measured directly and must be computed analytically from the temperature measured at test point 1 (TP1) shown in Figure 7-1 and the package thermal resistance in Section 7.6.
(5) Per Figure 6-1, 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 Section 7.7 for a definition of micromirror landed duty cycle.
(6) Long-term is defined as the usable life of the device
(7) 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 the long-term maximum and 75°C, and less than 500 hours for temperatures between 0°C and –20°C.
(8) Temperature delta is the highest difference between the ceramic test point 1 (TP1) and anywhere on the window edge as shown in Figure 7-1.
(9) Window temperature is the highest temperature on the window edge shown in Figure 7-1.
(10) The DLP2000 DMD is intended for use in well controlled, low dew point environments.  Please contact your local TI sales person or TI distributor representative to determine if this device is suitable for your application and operating environment compared other DMD solutions. DLP Products offers a broad portfolio of DMDs suitable for a wide variety of applications.
