The EL5120, EL5220, and EL5420 are low power, high voltage, rail-to-rail input-output amplifiers. The EL5120 contains a single amplifier, the EL5220 contains two amplifiers, and the EL5420 contains four amplifiers. Operating on supplies ranging from 5V to 15V, while consuming only 500A per amplifier, the EL5120, EL5220, and EL5420 have a bandwidth of 12MHz (-3dB). They also provide common mode input ability beyond the supply rails, as well as rail-to-rail output capability. This enables these amplifiers to offer maximum dynamic range at any supply voltage.
