tage, and low power consumption video dr iver with a built-in low pass filter. T he internal transparent clamp circuit c an restore composite video signal to fi xed DC level. IA 171 incorporates a hig h performance 4 stages Low Pass Filter that is ideal for removing DAC sampling noise. Only small ceramic capacitor (0 .1uF typical) is required for AC-couple d input. The output can be configured a s AC or DC-coupled output. With AC-coup led, sag correction can reduce output c oupling capacitance. With DC-coupled, i t can eliminate large output coupling c apacitors and save board space. It’s low voltage and low power consumption i s suitable for portable device. Ultra-l ow current consumption during power sav e to under 1uA. IA 171 can also be conf igured as bias inputs video driver when bias video signals are needed.
