operating mode.

(3)

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

reduce 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 10 and the package thermal resistance using Micromirror Array Temperature Calculation.

(5)

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.

(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 75ºC, and less than 500 hours for temperatures between 0ºC and –20ºC.

(8)

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

Figure 10.

(9)

Window temperature is the highest temperature on the window edge shown in Figure 10.

(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.
