EL1516, EL1516A
Dual Ultra Low Noise Amplifier
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.
The EL1516 features a -3dB bandwidth of 350MHz @ AV = -1
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.
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.

Applications Information
T JMAX = T MAX + JA PD MAXTOTAL
Product Description
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 currentfeedback 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, sampleand-holds, or integrators.
ADSL CPE Applications
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.

• PDMAXTOTAL is the sum of the maximum power dissipation
of each amplifier in the package (PDMAX)
• PDMAX for each amplifier can be calculated as follows:
V OUTMAX
PDMAX = 2 V S I SMAX + V S – V OUTMAX ---------------------------RL
(EQ. 2)
where:
• TMAX = Maximum ambient temperature
• JA = Thermal resistance of the package
• PDMAX = Maximum power dissipation of 1 amplifier
• VS = Supply voltage
• IMAX = Maximum supply current of 1 amplifier
• VOUTMAX = Maximum output voltage swing of the
application
• RL = Load resistance
To serve as a guide for the user, we can calculate maximum
allowable supply voltages for the example of the video
cable-driver below since we know that TJMAX = +150°C, TMAX
= +75°C, ISMAX = 7.7mA, and the package JAs are shown in
Table 1. If we assume (for this example) that we are driving a
back-terminated video cable, then the maximum average value
(over duty-cycle) of VOUTMAX is 1.4V, and RL = 150, giving
the results seen in Table 1.

Power Dissipation
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 the
maximum junction temperature (TJMAX) for all applications to
determine if power supply voltages, load conditions, or
package type need to be modified for the EL1516 to remain in
the safe operating area. These parameters are related as
follows:

(EQ. 1)
where:
Single-Supply Operation
The EL1516 has been designed to have a wide input and
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 of
ground (RL = 500), and the lower output voltage range is
within 875mV of ground. Upper input voltage range reaches
3.6V, and output voltage range reaches 3.8V with a 5V supply
and RL = 500. This results in a 2.625V output swing 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
Printed-Circuit Layout
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 1000 load.
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 5k 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 lowinductance for best performance.
Output Drive Capability
The EL1516 has been designed to drive low impedance loads.
It can easily drive 6VPP into a 100 load. This high output
drive capability makes the EL1516 an ideal choice for RF, IF
and video applications.
