® Data Sheet 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.
