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.

The EL5420 is available in the space-saving 14-pin TSSOP

package, the industry-standard 14-pin SO package, as well

as the 16-pin QFN package. The EL5220 is available in the

8-pin MSOP package and the EL5120 is available in the 5-

pin TSOT and 8-pin HMSOP packages. All feature a

standard operational amplifier pin out. These amplifiers are

specified for operation over the full -40°C to +85°C

temperature range.
