EL5027
FN7426.0
Dual 2.5MHz Rail-to-Rail Input-Output
Buffer
The EL5027 is a dual, low power, high voltage rail-to-rail
input-output buffer. Operating on supplies ranging from 5V to
15V, while consuming only 110µA per channel, the EL5027
has a bandwidth of 2.5MHz -(-3dB). The EL5027 also
provides rail-to-rail input and output ability, giving the
maximum dynamic range at any supply voltage.
The EL5027 also features fast slewing and settling times, as
well as a high output drive capability of 30mA (sink and
source). These features make the EL5027 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 EL5027 is available in space-saving 6-pin TSOT
package and operates over a temperature range of -40°C to
+85°C.
