AAT7202 PDF Datasheet – 12+1 Channel Buffer

A buffer for a TFT (Thin-Film Transistor) LCD (Liquid Crystal Display) is an electronic circuit or component that serves as an interface between the display’s control signals and the actual LCD pixels. The purpose of a buffer in this context is to improve the efficiency of data transfer, signal integrity, and driving capabilities for the pixels in the display.

TFT LCDs are widely used in various electronic devices such as smartphones, computer monitors, TVs, and more. These displays require precise control signals to ensure accurate and high-quality image representation.

The AAT7200 consists of 12+1 channel buffers target toward the needs of thin film transistor liquid crystal display (TFT LCD). This device consist of a Vcom buffer circuits, four rail to rail buffer amplifiers circuits and 8 buffer amplifiers circuits. Each buffer is capable of driving heavy capacitive loads and offers fast load current (Vcom : 100mA, the others : 30mA).


1. 12 Channels with Output Current: +30mA (MAX)

2. 1 Vcom with Output Current: +100mA(MAX)

3. Unity Gain Buffer Capable of Driving Large Capacitive Loads

4. Input range Matched to LCD Reference Requirements

5. Specified for -20° C to +85 °C…6.5V to 16V
