The EL2227 is a dual, low-noise amplifier from Intersil, ideally suited to line receiving applications in ADSL and HDSLII designs. The product has a low noise specification of just 1.9nV/√Hz and 1.2pA/√Hz, making it ideal for the detection of very low amplitude signals. The EL2227 features a -3dB bandwidth of 115MHz and is gain-of-2 stable. The product 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.
The EL2227 is a dual very low‑noise amplifier designed for line‑receiving applications such as ADSL and HDSLII. It provides a voltage noise of only 1.9 nV/√Hz and a current noise of 1.2 pA/√Hz, making it suitable for detecting very low amplitude signals.
The device operates from +2.5 V to +12 V, draws just 4.8 mA per amplifier, and works over a temperature range of –40 °C to +85 °C. It is offered in space‑saving 8‑lead MSOP and industry‑standard 8‑lead SOIC packages and includes extensive performance curves and electrical specifications.
