EL2227
FN7058.4
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 Ld MSOP
package as well as the industry-standard 8 Ld SOIC. It can
operate over the -40°C to +85°C temperature range.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination
finish, which is 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.
