EL5221
Dual 12MHz Rail-to-Rail Input-Output
Buffer
The EL5221 is a dual, low power, high voltage rail-to-rail
input-output buffer. Operating on supplies ranging from 5V to
15V, while consuming only 500A per channel, the EL5221
has a bandwidth of 12MHz
-
(-3dB). The EL5221 also
provides rail-to-rail input and output ability, giving the
maximum dynamic range at any supply voltage.
The EL5221 also features fast slewing and settling times, as
well as a high output drive capability of 30mA (sink and
source). These features make the EL5221 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 EL5221 is available in space-saving 6-pin SOT-23 and
8-pin MSOP packages and operates over a temperature
range of -40C to +85C.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
