The internal transparent clamp circuit can restore composite video signal to fixed DC level. IA 171 incorporates a high 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-coupled input. The output can be configured as AC or DC-coupled output. With AC-coupled, sag correction can reduce output coupling capacitance. With DC-coupled, it can eliminate large output coupling capacitors and save board space. It’s low voltage and low power consumption is suitable for portable device. Ultra-low current consumption during power save to under 1uA. IA 171 can also be configured as bias inputs video driver when bias video signals are needed. Absolute Maximum Rating Supply Voltage...
