EL2228C

EL2228C - Preliminary EL2228C - Preliminary Dual Low Noise Amplifier Features Voltage noise of only 4.9nV/√Hz Current noise of only 1.2pA/√Hz Bandwidth (-3dB) of 80MHz @AV = +1 Gain-of-1 stable Just 4.5mA 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 4.9nV/ √ Hz and 1.2pA/ √ Hz, making it ideal for processing low voltage waveforms. The EL2228C has a -3dB bandwidth of 80MHz and is gain-of-1 stable. It also affords minimal power dissipation with a supply current of just 4.5mA 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.
