EL2228
FN7008.1
Dual Low Noise Amplifier
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-pin MSOP
package as well as the industry-standard 8-pin SO. It is
specified for operation over the -40°C to +85°C temperature
range.

NOTE: Intersil Pb-free 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.
