GENERAL DESCRIPTION
The AD8045 is a unity gain stable voltage feedback amplifier
with ultralow distortion, low noise, and high slew rate. With a
spurious-free dynamic range of −90 dBc @ 20 MHz, the
AD8045 is an ideal solution in a variety of applications,
including ultrasound, ATE, active filters, and ADC drivers.
ADI’s proprietary next generation XFCB process and innovative
architecture enables such high performance amplifiers.
The AD8045 features a low distortion pinout for the LFCSP,
which improves second harmonic distortion and simplifies the
layout of the circuit board.
The AD8045 has 1 GHz bandwidth, 1350 V/µs slew rate, and
settles to 0.1% in 7.5 ns. With a wide supply voltage range (3.3 V
to 12 V) and low offset voltage (200 µV), the AD8045 is an ideal
candidate for systems that require high dynamic range, preci-
sion, and high speed.
The AD8045 amplifier is available in a 3 mm × 3 mm LFCSP
and the standard 8-lead SOIC. Both packages feature an
exposed paddle that provides a low thermal resistance path to
the PCB. This enables more efficient heat transfer, and increases
reliability. The AD8045 works over the extended industrial
temperature range (−40°C to +125°C).

ABSOLUTE MAXIMUM RATINGS
Table 3.
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.
THERMAL RESISTANCE
θJA is specified for the worst-case conditions, i.e., θJA is specified
for device soldered in circuit board for surface-mount packages.
Table 4. Thermal Resistance
Maximum Power Dissipation
The maximum safe power dissipation for the AD8045 is limited
by the associated rise in junction temperature (TJ) on the die. At
approximately 150°C, which is the glass transition temperature,
the properties of the plastic change. Even temporarily exceeding
this temperature limit may change the stresses that the package
exerts on the die, permanently shifting the parametric perform-
ance of the AD8045. Exceeding a junction temperature of
175°C for an extended period of time can result in changes in
silicon devices, potentially causing degradation or loss of
functionality.
The power dissipated in the package (PD) is the sum of the qui-
escent power dissipation and the power dissipated in the die
due to the AD8045 drive at the output. The quiescent power is
the voltage between the supply pins (VS) times the quiescent
current (IS).
PD = Quiescent Power + (Total Drive Power – Load Power)
OUT
OUTSSDR–RIVP⎟⎟⎠⎜⎜⎝×+×=
RMS output voltages should be considered. If RL is referenced to
−VS, as in single-supply operation, 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. )SDRIVP4+×=
In single-supply operation with RL referenced to −VS, worst case
is VOUT = VS/2.
Airflow increases heat dissipation, effectively reducing θJA.
Also, more metal directly in contact with the package leads and
exposed paddle from metal traces, through holes, ground, and
power planes reduce θJA.
Figure 4 shows the maximum safe power dissipation in the
package versus the ambient temperature for the exposed paddle
SOIC (80°C/W) and LFCSP (93°C/W) package on a JEDEC
standard 4-layer board. θJA values are approximations.

ESD 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 this product features
