„ GENERAL DESCRIPTION
With features of 20V/μs high slew rate and
200ns of fast settling time, as well as 30mA
(sink and source) of high output driving
capability, the EC5420 is ideal for the
requirements of flat panel Thin Film Transistor
Liquid Crystal Displays (TFT-LCD) panel
reference buffers application. Due to
insensitive to power supply variation, EC5420
offers flexibility of use in multitude of
applications such as battery power, portable
devices and anywhere low power consumption
is concerned. With standard operational
amplifier pin assignment, the EC5420 is
offered in space saving 14-Pin TSSOP package
and specified over the -40°C to +85°C
temperature range.

The EC5420 is a 30mA output current
rail-to-rail quad channels operational amplifier
with wide supply range from 4.5V to 18V while
consumes only 750uA per channel. It provides
0.5V beyond the supply rails of common mode
input range and capability of rail-to-rail output
swing as well. This enables the amplifier to
offer maximum dynamic range at any supply
voltage among many applications. A 8MHz gain
bandwidth product allows EC5420 to perform
more stable than other devices in Internet
applications.
