General Description
The EL2227C 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 EL2227C is per-
fect for the detection of very low amplitude signals.
The EL2227C features a -3dB bandwidth of 115MHz and is gain-of-2
stable. The EL2227C also affords minimal power dissipation with a
supply current of just 4.8mA per amplifier. The amplifier can be pow-
ered from supplies ranging from ±2.5V to ±12V.
The EL2227C 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.
