GENERAL DESCRIPTION

The AD8029 (single), AD8030 (dual), and AD8040 (quad) are
rail-to-rail input and output high speed amplifiers with a
quiescent current of only 1.3 mA per amplifier. Despite their
low power consumption, the amplifiers provide excellent
performance with 125 MHz small signal bandwidth and
60 V/µs slew rate. ADI’s proprietary XFCB process enables high
speed and high performance on low power.
This family of amplifiers exhibits true single-supply operation
with rail-to-rail input and output performance for supply
voltages ranging from 2.7 V to 12 V. The input voltage range
extends 200 mV beyond each rail without phase reversal. The
dynamic range of the output extends to within 40 mV of each
rail.
The AD8029/AD8030/AD8040 provide excellent signal quality
with minimal power dissipation. At G = +1, SFDR is –72 dBc at
1 MHz and settling time to 0.1% is only 80 ns. Low distortion
and fast settling performance make these amplifiers suitable
drivers for single-supply A/D converters.
The versatility of the AD8029/AD8030/AD8040 allows the user
to operate the amplifiers on a wide range of supplies while
consuming less than 6.5 mW of power. These features extend
the operation time in applications ranging from battery-
powered systems with large bandwidth requirements to high
speed systems where component density requires lower power
dissipation.
The AD8029/AD8030 are the only low power, rail-to-rail input
and output high speed amplifiers available in SOT23 and SC70
micro packages. The amplifiers are rated over the extended
industrial temperature range, –40°C to +125°C.

ABSOLUTE MAXIMUM RATINGS
Table 4. AD8029/AD8030/AD8040 Stress Ratings

Stresses above those listed under Absolute Maximum Ratings
may cause permanent 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.
MAXIMUM POWER DISSIPATION

The maximum safe power dissipation in the AD8029/AD8030/
AD8040 package is limited by the associated rise in junction
temperature (TJ) on the die. The plastic encapsulating the die
locally reaches the junction temperature. At approximately
150°C, which is the glass transition temperature, the plastic
changes its properties. Even temporarily exceeding this
temperature limit may change the stresses that the package
exerts on the die, permanently shifting the parametric
performance of the AD8029/AD8030/AD8040. Exceeding a
junction temperature of 175°C for an extended period can
result in changes in silicon devices, potentially causing failure.
The still-air thermal properties of the package and PCB (θJA),
ambient temperature (TA), and the total power dissipated in the
package (PD) determine the junction temperature of the die. The
junction temperature can be calculated as
TJ = TA + (PD × θJA)
The power dissipated in the package (PD) is the sum of the
quiescent power dissipation and the power dissipated in the
package due to the load drive for all outputs. The quiescent
power is the voltage between the supply pins (VS) times the
quiescent current (IS). Assuming the load (RL) is referenced to
midsupply, the total drive power is VS/2 × IOUT, some of which is
dissipated in the package and some in the load (VOUT × IOUT).
The difference between the total drive power and the load
power is the drive power dissipated in the package.
PD = Quiescent Power + (Total Drive Power – Load Power)
OUT
OUTSSSDRVIVP–2⎟⎟⎠⎜⎜⎝×+×=
RMS output voltages should be considered. If RL is referenced to
VS–, as in single-supply operation, then the total drive power is
VS × IOUT.
If the rms signal levels are indeterminate, consider the worst
case, when VOUT = VS/4 for RL to midsupply: ()SSDRIVP4/+×=
In single-supply operation with RL referenced to VS–, worst case
is VOUT = VS/2.
Airflow will increase heat dissipation, effectively reducing θJA.
Also, more metal directly in contact with the package leads
from metal traces, through holes, ground, and power planes will
reduce the θJA. Care must be taken to minimize parasitic capaci-
tances at the input leads of high speed op amps, as discussed in
the PCB Layout section.
Figure 6 shows the maximum safe power dissipation in the
package versus the ambient temperature for the SOIC-8
(125°C/W), SOT23-8 (160°C/W), SOIC-14 (90°C/W),
TSSOP-14 (120°C/W), and SC70-6 (208°C/W) packages on a
JEDEC standard 4-layer board. θJA values are approximations.
