Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.
Continuous output current is tested with one output at a time.
See the Thermal Shutdown with Temperature Hysteresis section.
A series resistor can extend load capacitance range. The settling time can be optimized by a small series resistance. See
the Applications Information section for more information.

Detailed Description
The MAX9650/MAX9651 operational rail-to-rail
input/output amplifiers hold the VCOM voltage stable
while providing the ability to source and sink a high current quickly (1.3A) into a capacitive load such as the
backplane of a TFT-LCD panel.
Thermal Shutdown
with Temperature Hysteresis
The MAX9650/MAX9651 are capable of high output
currents and feature thermal-shutdown protection with
temperature hysteresis. When the die temperature
reaches +170°C, the device shuts down. When the die
cools down by 15°C, the device turns on again. In a
TFT-LCD application, the duty cycle is very low. Even
with high values of voltage and current, the power dissipation is low and the chip does not shut down.

MAX9650/MAX9651
Pin Description
Applications Information
Output Load
The MAX9650/MAX9651 are designed to drive capacitive loads. A small value of series resistance improves
the performance of the device to ensure stability and
fast settling with very large or very small capacitive
loads. In many cases, this resistance is already present
due to connection resistance in the wiring and no additional physical resistor is necessary. For minimum
series resistance required for stability with capacitive
loading, see Figure 2.
Power Supplies and Bypass Capacitors
The MAX9650/MAX9651 operate from a 6V to 20V single supply or from ±4.5V to ±10V dual supplies. Proper
supply bypassing ensures stability while driving high
transient loads. The MAX9650/MAX9651 require a minimum 10µF (C1) and 0.1µF (C2) power-supply bypass
capacitors placed as close as possible to the powersupply pin (VDD). See Figure 3. For dual-supply operation, use 10µF and 0.1µF bypass capacitors on both
supplies (VDD and GND) with each capacitor placed as
close as possible to VDD and GND.
Layout and Grounding
The exposed pad on the µMAX® and TDFN packages
provide a low thermal resistance for heat dissipation.
Solder the exposed pad to a ground plane for best
thermal performance. Do not route traces under these
packages. For dual-supply operation, the exposed pad
(EP) can be electrically connected to the negative supply or it can be left unconnected.
