pose amplifier. It also can be used to replace high speed amplifiers consuming more power. The AD8011 is a current feedback amplifier and features gain flatness of 0.1 dB to 25 MHz while offering differential gain and phase error of 0.02% and 0.06° on a single +5 V supply. This makes the AD8011 ideal for professional video electronics such as cameras, video switchers or any high speed portable equipment. Additionally, the AD8011's low distortion and fast settling make it ideal for buffering high speed 8-, 10-, 12-bit A-to-D converters. The AD8011 offers very low power of 1 mA max and can run on single +5 V to +12 V supplies. All this is offered in a small 8-pin DIP or 8-pin SOIC package. These features fit well with portable and battery powered applications where size and power are critical. The AD8011 is available in the industrial temperature range of 40°C to +85°C.

NOTES 1 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. 2 Specification is for device in free air: 8-Pin Plastic Package: JA = 90°C/Watt 8-Pin SOIC Package: JA = 140°C/Watt
The maximum power that can be safely dissipated by the AD8011 is limited by the associated rise in junction temperature. The maximum safe junction temperature for plastic encapsulated devices is determined by the glass transition temperature of the plastic, approximately +150°C. Exceeding this limit temporarily may cause a shift in 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. While the AD8011 is internally short circuit protected, this may not be sufficient to guarantee that the maximum junction temperature is not exceeded under all conditions. To ensure proper operation, it is necessary to observe the maximum power derating curves (shown below in Figure 3).

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 the AD8011 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.
