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. 19V SUPPLY *C2 = 0.1μF *C1 = 10μF 19V SUPPLY VDD MAX9650 VREF LCD VCOM LOAD IN_+ OUT_ VOUT_ IN_- RS = 2.2Ω CLCD = 0.1μF **0V TO 2.2V AT 50kHz GND *10μF and 0.1μF CAPACITORS AS CLOSE AS POSSIBLE TO THE PIN. **(RS = RGEN) x CLCD x 6 < 2μs, WHERE RGEN = GENERATOR SOURCE IMPEDANCE. Figure 1. Settling Time Test Circuit _______________________________________________________________________________________ 5 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. 16V SUPPLY 2.0 *C2 = 0.1μF 1.8 *C1 = 10μF 19V SUPPLY 1.6 RESISTANCE (Ω) MAX9650/MAX9651 High-Current VCOM Drive Op Amps for TFT LCDs VDD 1.4 STABLE 1.2 MAX9650 1.0 VREF TFT LCD IN_+ OUT_ 0.8 0.6 IN_- 0.4 UNSTABLE 0.2 **RS TFT-LCD CAPACITANCE GND 0 10-7 10-6 10-5 10-4 CAPACITANCE (F) Figure 2.
