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/ m s 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 m A
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 m V/°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 W or 50 W series terminated lines and still maintain more
than 135 MHz, 3 dB bandwidth.

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.

extended periods may affect device reliability.

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.

APPLICATIONS
CD ROM and DVD Photodiode Preamp
High speed Multi-X CD ROM and DVD drives require high
frequency photodiode preamps for their read channels. To mini-
mize the effects of the photodiode capacitance, the low imped-
ance of the inverting input of a current feedback amplifier is
advantageous. Good group delay characteristics will preserve the
pulse response of these pulses. The AD8014, having many ad-
vantages, can make an excellent low cost, low noise, low power,
and high bandwidth photodiode preamp for these applications.
Figure 21 shows the circuit that was used to imitate a photo-
diode preamp. A photodiode for this application is basically a
high impedance current source that is shunted by a small ca-
pacitance. In this case, a high voltage pulse from a Picosecond
Pulse Labs Generator that is ac-coupled through a 20 kW resis-
tor is used to simulate the high impedance current source of a
photodiode. This circuit will convert the input voltage pulse into
a small charge package that is converted back to a voltage by the
AD8014 and the feedback resistor.
In this case the feedback resistor chosen was 1.74 kW , which is a
compromise between maintaining bandwidth and providing
sufficient gain in the preamp stage. The circuit preserves the
pulse shape very well with very fast rise time and a minimum of
overshoot as shown in Figure 22.

DRIVING CAPACITIVE LOADS
The AD8014 was designed primarily to drive nonreactive loads.
If driving loads with a capacitive component is desired, best
settling response is obtained by the addition of a small series
resistance as shown in Figure 26. The accompanying graph
shows the optimum value for RSERIES vs. Capacitive Load. It is
worth noting that the frequency response of the circuit when
driving large capacitive loads will be dominated by the passive
roll-off of RSERIES and CL.

Figure 26. Driving Capacitive Load
Choosing Feedback Resistors
Changing the feedback resistor can change the performance of
the AD8014 like any current feedback op amp. The table below
illustrates common values of the feedback resistor and the per-
formance which results.

Video Drivers
The AD8014 easily drives series terminated cables with video
signals. Because the AD8014 has such good output drive you
can parallel two or three cables driven from the same AD8014.
Figure 23 shows the differential gain and phase driving one
video cable. Figure 24 shows the differential gain and phase
driving two video cables. Figure 25 shows the differential gain
and phase driving three video cables.
