14+1 Channel Voltage Buffers for TFT LCD
APPLICATIONS INFORMATION
Product Description

range made itself an ideal amplifier for use in a wide
range of general-purpose applications. The features
of 1µS high slew rate, fast settling time, 2MHz of
GBWP as well as high output driving capability have
proven the EC5575 a good voltage reference buffer in
TFT-LCD for grayscale reference applications. High
Output Phase Reversal
The EC5575 is designed to prevent its output from
being phase reversal as long as the input voltage is
limited from VS- 0.5V to VS+ 0.5V. Figure 2 shows
a photo of the device output with its input voltage
phase margin and extremely low power consumption driven beyond the supply rails. Although the phase of

result in an over stress damage.
The EC5575 can be operated with a single nominal
wide supply voltage ranging from 6.5V to 18V with
stable performance over operating temperatures of
-20 °C to +85 °C.
With 500mV greater than rail-to-rail input common
mode voltage range and 75dB of Common Mode
Rejection Ratio, the EC5575 allows a wide range
sensing among many applications without having any
concerns over exceeding the range and no
compromise in accuracy. The output swings of the
EC5575 typically extend to within 80mV of positive
and negative supply rails with load currents of 5mA.
The output voltage swing can be even closer to the Figure 2. Operation with Beyond-the Rails Inputhttp:w//wwww.wD.aDtaaStahSehete.neet4t/U.net/

voltage swing can be easily achieved.
For the high drive amplifier EC5575, it is possible to
exceed the 'absolute-maximum junction temperature'
under certain load current conditions. Therefore, it is
important to calculate the maximum junction
temperature for the application to determine if load
conditions need to be modified for the amplifier to
remain in the safe operating area. The maximum
power dissipation allowed in a package is determined
according to:
PDmax
=
TJmax - TAmax
ΘJA

Output Short Circuit Current Limit
A +/-120mA short circuit current will be limited by the
EC5575 if the output is directly shorted to the positive
or the negative supply. For an indefinitely output short
circuit, the power dissipation could easily increase
such that the device may be damaged. The internal
