AD8042
The output voltage swing extends to within 30 mV of each rail, providing the maximum output dynamic range. Additionally, it features gain flatness of 0.1 dB to 14 MHz while offering differential gain and phase error of 0.04% and 0.06° on a single +5 V supply. This makes the AD8042 useful for professional video electronics such as cameras, video switchers or any high speed portable equipment. The AD8042's low distortion and fast settling make it ideal for buffering single supply, high speed A-to-D converters. The AD8042 offers low power supply current of 12 mA max and can run on a single +3.3 V power supply. These features are ideally suited for portable and battery powered applications where size and power are critical. The wide bandwidth of 160 MHz along with 200 V/µs of slew rate on a single +5 V supply make the AD8042 useful in many general purpose, high speed applications where single supplies from +3.3 V to +12 V and dual power supplies of up to ±6 V are needed. The AD8042 is available in 8-lead plastic DIP and SOIC.

NOTES 1 Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; 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 the device in free air: 8-Lead Plastic DIP Package: JA = 90°C/W 8-Lead SOIC Package: JA = 155°C/W
While the AD8042 is internally short circuit protected, this may not be sufficient to guarantee that the maximum junction temperature (+150°C) is not exceeded under all conditions. To ensure proper operation, it is necessary to observe the maximum power derating curves.

The maximum power that can be safely dissipated by the AD8042 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.

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 AD8042 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.
