General Description
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.
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.
