Detailed Description
The MAX9550/MAX9551/MAX9552 operational transcon-
ductance amplifiers (OTA) hold the VCOM voltage sta-
ble while providing the ability to source and sink a high
current quickly (800mA typ) into a capacitive load such
as the backplane of a TFT-LCD panel. The output settles
to within 0.1% in less than 2s. The fast settling time is
achieved by increasing the transconductance of the
buffer as the output current increases (see the Typical
Operating Characteristics).
In addition, the MAX9550/MAX9551/MAX9552 directly
drive the capacitive load in the VCOM layer of the
TFT LCD without the need for a series resistor.
The MAX9550/MAX9551/MAX9552 unity-gain band-
width is:
GBW = gM OUT
where COUT is the capacitive load at the output and gM
is the transconductance.
To insure buffer stability, place a 1F low-ESR capaci-
tor as close to the OUT pin as possible. However, this
value may be reduced if the TFT-LCD panel load pro-
vides some of the capacitance and the resistance in
series when this capacitance is low. Connect the feed-
back at OUT using a Kelvin connection at the low-ESR
capacitor.
Thermal Shutdown with Temperature
Hysteresis
The MAX9550/MAX9551/MAX9552 are capable of high
output currents and therefore, feature thermal-shutdown
protection with temperature hysteresis. When the die tem-
perature reaches +160°C, the devices shut down. When
the die cools down by 15°C, the devices turn on again.
