Amplifiers are ideal for large panel
displays
The MAX9550, MAX9551 and MAX9552 VCOM drive buffers for TFT-LCD panels feature single-, dual- and quad-channel VCOM amplifiers, respectively.
Maxim Integrated Products has introduced the MAX9550, MAX9551 and MAX9552 VCOM drive buffers for TFT-LCD panels that feature single-, dual- and quad-channel VCOM amplifiers, respectively The MAX9550, MAX9551 and MAX9552 source and sink up to 800mA per channel to quickly restore the VCOM voltage, making them ideal for large panels

Speedy DAC claims dynamic superiority for comms
The MAX5195 is a 14bit 260Msample/s DAC claimed to provide the world's best dynamic performance in spurious-free dynamic range, intermodulation distortion and signal to noise ratio.
The MAX9550, MAX9551 and MAX9552 family buffers use the high current to quickly settle the VCOM to within 0.1% in less than 2us.
This longer period of accurate VCOM helps reduce flicker.
The MAX9550, MAX9551 and MAX9552 operate up to 20V for systems that require more than the typical 16.5V.
They can directly drive the capacitive load in the VCOM layer without the need for a series isolation resistor.
In addition these devices feature soft-start to reduce inrush current, output short-circuit protection, and thermal shutdown to sustain robust operation.
The MAX9550 is available in a space-saving, 5-pin thin SOT23 package and an 8-pin microMAX package with an exposed paddle for high-power applications.
The MAX9551 is available in an 8-pin microMAX package with an exposed paddle, and the MAX9552 is available in a 14-pin TSSOP package.
All devices are specified over the -40 to +85C temperature range.
