„ GENERAL DESCRIPTION
The EC5462 is a rail-to-rail dual channels
operational amplifier with wide supply range
from 4.5V to 16V. 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 EC5462 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 EC5462 is ideal for the
requirements of flat panel Thin Film Transistor
Liquid Crystal Displays (TFT-LCD) panel
grayscale reference buffers application. Due to
insensitive to power supply variation, EC5462
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 EC5462 is
offered in a space saving 8-Pin MSOP package
and specified over the -40°C to +85°C
temperature range.

„ ABSOLUTE MAXIMUM RATINGS (TA = 25 °C)
Values beyond absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only; functional device operation is not implied. Exposure to AMR conditions for extended periods may affect
