Product Summary

The AS15-HF is a 14+1 channel voltage buffer that buffers reference voltage for gamma correction in a thin film transistor liquid crystal display (TFT LCD). This device incorporating a Vcom amplifier circuits, four rail to rail buffer amplifier circuits (the highest two stage and lowest two stage) and 10 buffer amplifiers circuits. The AS15-HF is available in a space saving 48-pin TQFP package, and the operating temperature is from -20℃ to +85℃. The application of the AS15-HF includes TFT-LCD Reference Driver.
