Description IA171 is a high performance, low voltage, and low power consumption video driver with a built-in low pass filter. The internal transparent clamp circuit can restore posite 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 (0.1u F 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 1u A. IA 171 can also be configured as bias inputs video driver when bias video signals are...
