EL2227

Dual, Very Low Noise Amplifier

DATASHEET

The EL2227 is a dual, low-noise amplifier, ideally suited to

line receiving applications in ADSL and HDSLII designs.

With low noise specification of just 1.9nV/

Hz and

1.2pA/

Hz, the EL2227 is perfect for the detection of very

low amplitude signals.

The EL2227 features a -3dB bandwidth of 115MHz and is

gain-of-2 stable. The EL2227 also affords minimal power

dissipation with a supply current of just 4.8mA per amplifier.

The amplifier can be powered from supplies ranging from

±2.5V to ±12V.

The EL2227 is available in a space-saving 8 Ld MSOP

package as well as the industry-standard 8 Ld SOIC. It can

operate over the -40°C to +85°C temperature range.
