EL2228C Datasheet | Elantec Semiconductor

Features - Voltage noise of only 4.9n V/√Hz - Current noise of only 1.2p A/√Hz - Bandwidth (-3d B) of 80MHz @AV = +1 - Gain-of-1 stable - Just 4.5m A per amplifier - 8-pin MSOP package - ±2.5V to ±12V operation General Description The EL2228C is a dual, low-noise amplifier, ideally suited to filtering applications in ADSL and HDSLII designs. It feature low noise specification of just 4.9n V/ √ Hz and 1.2p A/ √ Hz, making it ideal for processing low voltage waveforms. The EL2228C has a -3d B bandwidth of 80MHz and is gain-of-1 stable. It also affords minimal power dissipation with a supply current of just 4.5m A 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.
