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
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.
