Quad Operational Amplifiers
EC5420A
Introduction
(General Description)
The EC5420A 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 EC5420A to perform
more stable than other devices in Internet
applications.
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 EC5420A 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, EC5420A 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 EC5420A is offered in space saving
14-Pin TSSOP package and specified over the -20°C
to +85°C temperature range.
