OPERATING TEMPERATURE RANGE

The maximum operating junction temperature is 150°C. The

junction temperature trip point of the thermal protection

circuit is 165°C. Production tests guarantee a minimum

junction temperature trip point of 125°C.

Consequently, the maximum guaranteed operating junction

temperature is 125°C when the thermal protection circuit is

enabled and 150°C when the thermal protection circuit is

disabled.

To ensure operation within the specified operating temperature

range, it is necessary to limit the maximum power dissipation as

Figure 2. Maximum Power Dissipation vs. Temperature

The AD8386 is on a 4-layer JEDEC PCB with a thermally

optimized landing pattern with 16 vias.

The quiescent power dissipation of the AD8386 is 1.4 W.

When driving a 12-channel 720p HDTV panel with an input

capacitance of 150 pF, the AD8386 dissipates 1.66 W when

displaying 1 pixel wide alternating white and black vertical lines

generated by a standard 720p HDTV input video.

Conditions include the following:

• AVCC = 15.5 V

• DVCC = 3.3 V

• VFS = 5 V

• C_L= 150 pF

• f_PIXEL= 74.25 MHz

• Black-to-white transition = 4 V

• Active video time = 75%

Figure 2 shows these power dissipations.
