Data Sheet May 3, 2007 FN7008.2
Dual Low Noise Amplifier
The EL2228 is a dual, low-noise amplifier, ideally suited to filtering applications in ADSL and HDSLII designs. It features low noise specification of just 4.9nV/Hz and 1.2pA/Hz, making it ideal for processing low voltage waveforms. The EL2228 has a -3dB bandwidth of 80MHz and is gainof-1 stable. It also affords minimal power dissipation with a supply current of just 4.5mA per amplifier. The amplifier can be powered from supplies ranging from 2.5V to 12V. The EL2228 is available in a space saving 8 Ld MSOP package as well as the industry-standard 8 Ld SOIC. It is specified for operation over the -40C to +85C temperature range.

Applications Information
Product Description
The EL2228 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 and is built on Elantec's proprietary high-speed complementary bipolar process. The EL2228 uses a classical voltage-feedback topology which allows them 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 EL2228 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.
excellent choice for single-supply operation. Using a single positive supply, the lower input voltage range is within 300mV 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 28V.
Gain-Bandwidth Product and the -3dB Bandwidth
The EL2228 has a gain-bandwidth product of 40MHz while using only 5mA of supply current per amplifier. For gains greater than 1, their closed-loop -3dB bandwidth is approximately equal to the gain-bandwidth product divided by the noise gain of the circuit. For gains of 1, higher-order poles in the amplifiers' transfer function contribute to even higher closed loop bandwidths. For example, the EL2228 have a -3dB bandwidth of 80MHz at a gain of 1, dropping to 9MHz at a gain of 5. It is important to note that the EL2228 is designed so that this "extra" bandwidth in low-gain
Single-Supply Operation
The EL2228 was designed to have a wide input and output voltage range. This design also makes the EL2228 an

application does not come at the expense of stability. As seen in the typical performance curves, the EL2228 in a gain of only 1 exhibited 0.5dB of peaking with a 500 load. 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
Output Drive Capability
The EL2228 is designed to drive a low impedance load. It can easily drive 6VP-P signal into a 500 load. This high output drive capability makes the EL2228 an ideal choice for RF, IF, and video applications. Furthermore, the EL2228 is current-limited at the output, allowing it to withstand momentary short to ground. However, the power dissipation with output-shorted cannot exceed the power dissipation capability of the package.
Driving Cables and Capacitive Loads
Although the EL2228 is designed to drive low impedance load, capacitive loads will decreases the amplifier's phase margin. As shown in the performance curves, capacitive load can result in peaking, overshoot and possible oscillation. For optimum AC performance, capacitive loads should be reduced as much as possible or isolated with a series resistor between 5 to 20. When driving coaxial cables, double termination is always recommended for reflection-free performance. When properly terminated, the capacitance of the coaxial cable will not add to the capacitive load seen by the amplifier.
Power Supply Bypassing And Printed Circuit Board Layout
As with any high frequency devices, good printed circuit board layout is essential for optimum performance. Ground plane construction is highly recommended. Pin lengths should be kept as short as possible. The power supply pins must be closely bypassed to reduce the risk of oscillation. The combination of a 4.7F tantalum capacitor in parallel with 0.1F ceramic capacitor has been proven to work well when placed at each supply pin. For single supply operation, where pin 4 (VS-) is connected to the ground plane, a single 4.7F tantalum capacitor in parallel with a 0.1F ceramic capacitor across pin 8 (VS+). For good AC performance, parasitic capacitance should be kept to a minimum. Ground plane construction again should be used. Small chip resistors are recommended to minimize series inductance. Use of sockets should be avoided since they add parasitic inductance and capacitance which will result in additional peaking and overshoot.
Power Dissipation
With the wide power supply range and large output drive capability of the EL2228, it is possible to exceed the 150C 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 EL2228 to remain in the safe operating area. These parameters are related as follows:
T JMAX = T MAX + ( JA xPD MAXTOTAL )
where: * 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 PD MAX = 2*V S x I SMAX + ( V S - V OUTMAX ) x --------------------------R
