EL2227C

Dual Very Low Noise Amplifier

Applications Information

choice for applications such as active filters, sample-

and-holds, or integrators.

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

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/ÖHz voltage noise and 1.2pA/ÖHz current noise

performance, -140dBm/Hz system background noise

performance can be easily achieved.
