Dual Ultra Low Noise Amplifier
Features
The EL1516 is a dual, ultra low noise amplifier, ideally suited
to line receiving applications in ADSL, VDSL, and home
PNA designs. With low noise specification of just 1.3nV/√Hz
and 1.5pA/√Hz, the EL1516 is perfect for the detection of
very low amplitude signals.
• EL2227 upgrade replacement
• Voltage noise of only 1.3nV/√Hz
• Current noise of only 1.5pA/√Hz
• Bandwidth (-3dB) of 350MHz @ A = -1
V
The EL1516 features a -3dB bandwidth of 350MHz @ A = -1
V
• Bandwidth (-3dB) of 250MHz @ A = +2
V
and is gain-of-2 stable. The EL1516 also affords minimal
power dissipation with a supply current of just 5.5mA per
amplifier. The amplifier can be powered from supplies ranging
from 5V to 12V.
• Gain-of-2 stable
• Just 5.5mA per amplifier
• 100mA I
OUT
The EL1516A incorporates an enable and disable function to
reduce the supply current to 5nA typical per amplifier,
allowing the EN pins to float or apply a low logic level will
enable the amplifiers.
• Fast enable/disable (EL1516A only)
• 5V to 12V operation
• Pb-free plus anneal available (RoHS compliant)
The EL1516 is available in space-saving 8 Ld MSOP and
industry-standard 8 Ld SOIC packages and the EL1516A is
available in a 10 Ld MSOP package. All are specified for
operation over the -40°C to +85°C temperature range.
Applications
• ADSL receivers
• VDSL receivers
Pinouts
• Home PNA receivers
• Ultrasound input amplifiers
• Wideband instrumentation
• Communications equipment
• AGC and PLL active filters
• Wideband sensors

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.

The EL1516 is a dual voltage feedback operational amplifier
designed especially for DMT ADSL and other applications
requiring very low voltage and current noise. It also features
low distortion while drawing moderately low supply current.
The EL1516 uses a classical voltage-feedback topology
which allows it to be used in a variety of applications where
current-feedback amplifiers are not appropriate because of
restrictions placed upon the feedback element used with the
amplifier. The conventional topology of the EL1516 allows,
for example, a capacitor to be placed in the feedback path,
making it an excellent choice for applications such as active
filters, sample-and-holds, or integrators.

The low noise EL1516 amplifier is specifically designed for
the dual differential receiver amplifier function with ADSL
transceiver hybrids as well as other low-noise amplifier
applications. A typical ADSL CPE line interface circuit is
shown in Figure 44. The EL1516 is used in receiving DMT
down stream signal. With careful transceiver hybrid design
and the EL1516 1.4nV/√Hz voltage noise and 1.5pA/√Hz
current noise performance, -140dBm/Hz system background
noise performance can be easily achieved.

Single-Supply Operation
The EL1516 has been designed to have a wide input and
Power Dissipation
output voltage range. This design also makes the EL1516 an
excellent choice for single-supply operation. Using a single
positive supply, the lower input voltage range is within 1.2V
With the wide power supply range and large output drive
capability of the EL1516, it is possible to exceed the +150°C
maximum junction temperatures under certain load and
power supply conditions. It is therefore important to calculate
of ground (R = 500Ω), and the lower output voltage range is
L
within 875mV of ground. Upper input voltage range reaches
3.6V, and output voltage range reaches 3.8V with a 5V
the maximum junction temperature (T
) for all
JMAX
applications to determine if power supply voltages, load
conditions, or package type need to be modified for the
supply and R = 500Ω. This results in a 2.625V output swing
L
on a single 5V supply. This wide output voltage range also
allows single-supply operation with a supply voltage as high
as 12V.

EL1516, EL1516A
Gain-Bandwidth Product and the -3dB Bandwidth
Output Drive Capability
The EL1516 has a gain-bandwidth product of 300MHz while
using only 6mA of supply current per amplifier. For gains
greater than 2, their closed-loop -3dB bandwidth is
approximately equal to the gain-bandwidth product divided
by the noise gain of the circuit. For gains less than 2, higher-
order poles in the amplifiers' transfer function contribute to
even higher closed loop bandwidths. For example, the
EL1516 has a -3dB bandwidth of 350MHz at a gain of +2,
dropping to 80MHz at a gain of +5. It is important to note that
the EL1516 has been designed so that this “extra” bandwidth
in low-gain applications does not come at the expense of
stability. As seen in the typical performance curves, the
EL1516 in a gain of +2 only exhibits 0.5dB of peaking with a
1000Ω load.
The EL1516 has been designed to drive low impedance
loads. It can easily drive 6V into a 100Ω load. This high
PP
output drive capability makes the EL1516 an ideal choice for
RF, IF and video applications.
Printed-Circuit Layout
The EL1516 is well behaved, and easy to apply in most
applications. However, a few simple techniques will help
assure rapid, high quality results. As with any high-frequency
device, good PCB layout is necessary for optimum
performance. Ground-plane construction is highly
recommended, as is good power supply bypassing. A 0.1µF
ceramic capacitor is recommended for bypassing both
supplies. Lead lengths should be as short as possible, and
bypass capacitors should be as close to the device pins as
possible. For good AC performance, parasitic capacitances
should be kept to a minimum at both inputs and at the
output. Resistor values should be kept under 5kΩ because
of the RC time constants associated with the parasitic
capacitance. Metal-film and carbon resistors are both
acceptable, use of wire-wound resistors is not recommended
because of their parasitic inductance. Similarly, capacitors
should be low-inductance for best performance.
