GENERAL DESCRIPTION

The AD8004 is a quad, low power, high speed amplifier designed to operate on single or dual supplies. It utilizes a current feed­back architecture and features high slew rate of 3000 V/ms making the AD8004 ideal for handling large amplitude pulses. Additionally, the AD8004 provides gain flatness of 0.1 dB to

30 MHz while offering differential gain and phase error of
0.04% and 0.10∞. This makes the AD8004 suitable for video electronics such as cameras and video switchers.
The AD8004 offers low power of 3.5 mA/amplifier and can run on a single +4 V to +12 V power supply, while being capable of delivering up to 50 mA of load current. All this is offered in a small 14-lead DIP or 14-lead SOIC package. These features make this amplifier ideal for portable and battery powered appli­cations where size and power are critical.
The outstanding bandwidth of 250 MHz along with 3000 V/ms of slew rate make the AD8004 useful in many general-purpose, high speed applications where dual power supplies of up to ±6V and single supplies from 4 V to 12 V are needed. The AD8004 is available in the industrial temperature range of –40∞C to +85∞C in the N and R packages, and in the military temperature range of –55∞C to +125∞C in the Q package.

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.

MAXIMUM POWER DISSIPATION

The maximum power that can be safely dissipated by the AD8004 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 AD8004 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 ratings.
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 AD8004 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.
