PRODUCT DESCRIPTION

The AD8044 is a quad low power, voltage feedback, high speed

amplifier designed to operate on +3 V, +5 V or ±5 V supplies.

It has true single-supply capability with an input voltage range extending 200 mV below the negative rail and within 1 V of the positive rail.

TOP VIEW

The output voltage swing extends to within 25 mV of each rail, providing the maximum output dynamic range. Additionally, it features gain flatness of 0.1 dB to 12 MHz while offering differ-

ential gain and phase error of 0.04% and 0.22° on a single +5 V

supply. This makes the AD8044 useful for video electronics such as cameras, video switchers or any high speed portable equipment. The AD8044’s low distortion and fast settling make it ideal for active filter applications.

The AD8044 offers low power supply current of 13.1 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 150 MHz along with 170 V/µs of slew

rate on a single +5 V supply make the AD8044 useful in many general purpose, high speed applications where dual power

supplies of up to ±6 V and single supplies from +3 V to +12 V

are needed. The AD8044 is available in 14-lead plastic DIP and SOIC.

NOTES

Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent 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.

Specification is for the device in free air:

14-Lead Plastic Package: θJA = 75°C/W 14-Lead SOIC Package: θJA = 120°C/W

MAXIMUM POWER DISSIPATION

The maximum power that can be safely dissipated by the AD8044 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 AD8044 is internally short circuit protected, this may not be sufficient to guarantee that the maximum junction tem-

perature (+150°C) is not exceeded under all conditions. To

ensure proper operation, it is necessary to observe the maximum power derating curves.

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 AD8016 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.
