PRODUCT DESCRIPTION
The AD8014 is a revolutionary current feedback operational
amplifier that attains new levels of combined bandwidth, power,
output drive and distortion. Analog Devices, Inc. uses a propri-
etary circuit architecture to enable the highest performance
amplifier at the lowest power. Not only is it technically superior,
but is low priced, for use in consumer electronics. This general
purpose amplifier is ideal for a wide variety of applications
including battery operated equipment.

The AD8014 is a very high speed amplifier with 400 MHz,
–3 dB bandwidth, 4000 V/µs slew rate, and 24 ns settling time.
The AD8014 is a very stable and easy to use amplifier with fast
overload recovery. The AD8014 has extremely low voltage and
current noise, as well as low distortion, making it ideal for use
in wide-band signal processing applications.
For a current feedback amplifier, the AD8014 has extremely
low offset voltage and input bias specifications as well as low
drift. The input bias current into either input is less than 15 µA
at +25°C with a typical drift of less than 50 nA/°C over the
industrial temperature range. The offset voltage is 5 mV max
with a typical drift less than 10 µV/°C.
For a low power amplifier, the AD8014 has very good drive
capability with the ability to drive 2 V p-p video signals on
75 Ω or 50 Ω series terminated lines and still maintain more
than 135 MHz, 3 dB bandwidth.

NOTES
1 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 listed in the operational section of this
specification is not implied. Exposure to Absolute Maximum Ratings for any
extended periods may affect device reliability.
2 Specification is for device in free air at 25°C.
8-Lead SOIC Package θJA = 155°C/W.
5-Lead SOT-23 Package θJA = 240°C/W.
MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the AD8014
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. This is approximately +150°C. Even temporarily ex-
ceeding this limit may cause a shift in parametric performance
due to a change in the stresses exerted on the die by the pack-
age. Exceeding a junction temperature of +175°C may result in
device failure.
The output stage of the AD8014 is designed for large load cur-
rent capability. As a result, shorting the output to ground or to
power supply sources may result in a very large power dissipa-
tion. To ensure proper operation it is necessary to observe the
maximum power derating tables.

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 AD8014 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.
