Data Sheet February 21, 2005

12MHz Rail-to-Rail Input-Output Op Amps

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 500µA 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.

The EL5120, EL5220, and EL5420 also feature fast slewing
and settling times, as well as a high output drive capability of
30mA (sink and source). These features make these
amplifiers ideal for use as voltage reference buffers in Thin
Film Transistor Liquid Crystal Displays (TFT-LCD). Other
applications include battery power, portable devices, and
anywhere low power consumption is important.
