EL5421

Quad 12MHz Rail-to-Rail Input-Output

Buffer

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.

Features

•12MHz -3dB bandwidth

•Unity gain buffer

•Supply voltage = 4.5V to 16.5V

•Low supply current (per buffer) = 500µA

•High slew rate = 10V/µs

•Rail-to-rail operation

•“Mini” SO package (MSOP)

•Pb-free plus anneal available (RoHS compliant)

Applications

•TFT-LCD drive circuits

•Electronics notebooks

•Electronics games

•Personal communication devices

•Personal digital assistants (PDA)

•Portable instrumentation
