ABSOLUTE MAXIMUM RATINGS

MAXIMUM POWER DISSIPATION

Table 3.

The maximum power that can be safely dissipated by the

AD8386 is limited by its junction temperature. The maximum

safe junction temperature for plastic encapsulated devices, as

determined by the glass transition temperature of the plastic, is

approximately 150°C. Exceeding this limit temporarily may

cause a shift in the parametric performance due to a change in

the stresses exerted on the die by the package. Exceeding a

junction temperature of 175°C for an extended period can

result in device failure.

OVERLOAD PROTECTION

3.7 W

The AD8386 overload protection circuit consists of an output

current limiter and a thermal protection circuit.

0°C to 85°C

–65°C to +125°C

300°C

When TSW is LOW, the thermal protection circuit is disabled,

and the output current limiter is turned on. The maximum

current at any one output of the AD8386 is internally limited to

100 mA average. In the event of a momentary short circuit

between a video output and a power supply rail (AVCC or

AGND), the output current limit is sufficiently low to provide

temporary protection.

Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only and functional operation of the device at these or

any other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.

When TSW is HIGH, the output current limiter, as well as the

thermal protection circuit, is turned on. The thermal protection

circuit debiases the output amplifier when the junction

temperature reaches the internally set trip point. In the event of

an extended short circuit between a video output and a power

supply rail, the output amplifier current continues to switch

between 0 mA and 100 mA typical with a period determined by

the thermal time constant and the hysteresis of the thermal trip

point. The thermal protection circuit limits the average junction

temperature to a safe level, which provides long-term

protection.

Ψ_JB= 13.8°C/W in still air (JEDEC STD, 4-layer PCB with 16 vias on Epad)

EXPOSED PADDLE

To ensure optimal thermal performance, the exposed paddle

must be electrically connected to an external plane, such as

AVCC or GND, as described in the Applications section.

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate

on the human body and test equipment and can discharge without detection. Although this product features

proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy

electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance

degradation or loss of functionality.
