EL5421

Quad 12MHz Rail-to-Rail Input-Output Buffer

DATASHEET

The EL5421 is a quad, low power, high voltage rail-to-rail

input-output buffer. Operating on supplies ranging from 5V to

15V, while consuming only 500µA per channel, the EL5421

has a bandwidth of 12MHz (-3dB). The EL5421 also

provides rail-to-rail input and output ability, giving the

maximum dynamic range at any supply voltage.

The EL5421 also features fast slewing and settling times, as

well as a high output drive capability of 30mA (sink and

source). These features make the EL5421 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 EL5421 is available in a space saving 10 Ld MSOP

package and operates over a temperature range of -40°C to

+85°C.
