Optimal, long-term performance and optical efficiency of the Digital Micromirror Device (DMD) can be affected by various application

parameters, including illumination spectrum, illumination power density, micromirror landed duty-cycle, ambient temperature (storage

and operating), DMD temperature, ambient humidity (storage and operating), and power on or off duty cycle. TI recommends that

application-specific effects be considered as early as possible in the design cycle.

(4)

Array Temperature is the worst-case of any test point shown in Figure 11, or the active array as calculated by the 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)

Short-term is defined as less than 500 hours over the usable life of the device.

(8)

Ceramic package temperature as measured at test point 3 (TP 3) in Figure 11.

(9)

As measured between any two points on the exterior of the package, or as predicted between any two points inside the micromirror

array cavity. Refer to the Micromirror Array Temperature Calculation for information related to calculating the micromirror array

temperature.

(10) Refer to Thermal Information and Micromirror Array Temperature Calculation.
