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.
