EL2228

Dual Low Noise Amplifier

DATASHEET

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 gain-

of-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 -40°C to +85°C temperature

range.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate

termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
