The EL2227 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 EL2227 use 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 EL2227 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.

FUNCTION  
Power Dissipation  
With the wide power supply range and large output drive  
capability of the EL2227, 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  
ADSL CPE Applications  
The low noise EL2227 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 38. The EL2227 is used in receiving DMT down  
stream signal. With careful transceiver hybrid design and the

The EL2227 is in the standard dual amplifier package without  
the enable/disable function. A simple way to implement the  
enable/disable function is depicted in Figure 39. When disabled,  
both the positive and negative supply voltages are disconnected  
(see Figure 39).
