Applications Information
Product Description
The EL2227C 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 mod-
erately low supply current and is built on Elantec's
proprietary high-speed complementary bipolar process.
The EL2227C 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 ele-
ment used with the amplifier. The conventional topology
of the EL2227C 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.
ADSL CPE Applications
The low noise EL2227C 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 1. The EL2227C
is used in receiving DMT down stream signal. With
careful transceiver hybrid design and the EL2227C
1.9nV/
√Hz voltage noise and 1.2pA/√Hz current noise
performance, -140dBm/Hz system background noise
performance can be easily achieved.
