(1) The following power supplies are all required to operate the DMD: VDD, VDDI, VOFFSET, VBIAS, and VRESET. All VSS connections are also required.
(2) Recommended Operating Conditions are applicable after the DMD is installed in the final product.
(3) All voltage values are with respect to the ground pins (VSS).
(4) VOFFSET supply transients must fall within specified max voltages.
(5) To prevent excess current, the supply voltage delta |VDDI – VDD| must be less than the specified limit.
(6) To prevent excess current, the supply voltage delta |VBIAS – VOFFSET| must be less than the specified limit.
(8) Temperature Diode is to allow accurate measurement of the DMD array temperature during operation.
(10) The maximum operation conditions for operating temperature and UV illumination shall not be implemented simultaneously.
(11) Operating profile information for device micromirror landed duty-cycle and temperature may be provided if requested.
(12) The active area of the DLP5531-Q1 device is surrounded by an aperture on the inside of the DMD window surface that masks structures of the DMD device assembly from normal view. The aperture is sized to anticipate several optical conditions. Overfill light illuminating the area outside the active array can scatter and create adverse effects to the performance of an end application using the DMD. The illumination optical system should be designed to minimize light flux incident outside the active array. Depending on the particular system's optical architecture and assembly tolerances, the amount of overfill light on the outside of the active array may cause system performance degradation.
