EL2227C Datasheet | Elantec Semiconductor

Dual Very Low Noise Amplifier Features - Voltage noise of only 1.9n V/√Hz - Current noise of only 1.2p A/√Hz - Bandwidth (-3d B) of 115MHz @AV = +2 - Gain-of-2 stable - Just 4.8m A per amplifier - 8-pin MSOP package - ±2.5V to ±12V operation 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 1.9n V/√Hz and 1.2p A/√Hz, the EL2227C is perfect for the detection of very low amplitude signals. The EL2227C Features a -3d B bandwidth of 115MHz and is gain-of-2 stable. The EL2227C also affords minimal power dissipation with a supply current of just 4.8m A per amplifier. The amplifier can be powered 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.
