Features

low noise specification of just 4.9nV/√Hz and 1.2pA/√Hz, making it ideal for processing low voltage waveforms. The EL2228 has a -3dB bandwidth of 80MHz and is gainof-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 EL2228 is available in a space saving 8 Ld MSOP package as well as the industry-standard 8 Ld SOIC. It is specified for operation over the -40°C to +85°C temperature range.
