EL5027
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.
Features
· 2.5MHz -3dB bandwidth
· Unity gain buffer
· Supply voltage = 4.5V to 16.5V
· Low supply current (per buffer) = 110µA
· High slew rate = 1.2V/µs
· Rail-to-rail operation
· Pb-free available (RoHS compliant)
Applications
· TFT-LCD drive circuits
· Electronics notebooks
· Electronics games
· Personal communication devices
· Personal Digital Assistants (PDA)
· Portable instrumentation
· Wireless LANs
· Office automation
· Active filters
· ADC/DAC buffer

NOTE: Intersil Pb-free 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-020C.
