General Description

The EL5420C and EL5220C are low power, high voltage, rail-to-rail input-output amplifiers. The EL5220C contains two amplifiers in one package, and the EL5420C contains four amplifiers. Operating on supplies ranging from 5V to 15V, while consuming only 500µA peramplifier, the EL5420C and EL5220C 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.
