General Description
The EL2228C is a dual, low-noise amplifier, ideally suited to filtering
applications in ADSL and HDSLII designs. It feature low noise speci-
fication of just 4.9nV/√Hz and 1.2pA/√Hz, making it ideal for
processing low voltage waveforms.
The EL2228C has a -3dB bandwidth of 80MHz and is gain-of-1 sta-
ble. 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 EL2228C 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.
