PRODUCT DESCRIPTION
The AD8041 is a low power voltage feedback, high speed am-
plifier designed to operate on +3 V, +5 V or ±5 V supplies. It
has true single supply capability with an input voltage range
extending 200mV below the negative rail and within 1V of the
positive rail.
2.5V
Figure 1.Output Swing:Gain = –1, VS = +5 V
The output voltage swing extends to within 50 mV of each rail,
providing the maximum output dynamic range. Additionally, it
features gain flatness of 0.1 dB to 30 MHz while offering differ-
ential gain and phase error of 0.03% and 0.03° on a single +5 V
supply. This makes the AD8041 ideal for professional video
electronics such as cameras, video switchers or any high speed
portable equipment. The AD8041’s low distortion and fast set-
tling make it ideal for buffering high speed A-to-D converters.
The AD8041 has a high speed disable feature useful for mul-
tiplexing or for reducing power consumption (1.5 mA). The dis-
able logic interface is compatible with CMOS or open-collector
logic. The AD8041 offers low power supply current of 5.8 mA
max and can run on a single +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 160 V/μs of slew
rate on a single +5 V supply make the AD8041 useful in many
general purpose high speed applications where dual power sup-
plies of up to ±6 V and single supplies from +3 V to +12 V are
needed. The AD8041 is available in 8-pin plastic DIP and
SOIC over the industrial temperature range of –40°C to +85°C.

NOTES
1Stresses 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.

8-Pin Plastic Package: θJA = 90°C/Watt
8-Pin SOIC Package: θJA = 160°C/Watt.

MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the
AD8041 is limited by the associated rise in junction tempera-
ture. The maximum safe junction temperature for plastic encap-
sulated devices is determined by the glass transition temperature
of the plastic, approximately +150°C. Exceeding this limit tem-
porarily may cause a shift in parametric performance due to a
change in the stresses exerted on the die by the package. Ex-
ceeding a junction temperature of +175°C for an extended pe-
riod can result in device failure.
While the AD8041 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 en-
sure proper operation, it is necessary to observe the maximum
power derating curves.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD8041 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.
