EL2227
Dual Very Low Noise Amplifier
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-pin MSOP
package as well as the industry-standard 8-pin SO. It can
operate 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.
