Intersil has released the ISL59118, a 9 MHz, dual-channel, low-pass filter that eliminates video glitch noise associated with the use of video DACs.
This device uses nearly 50% less bias current than its previous generation devices. Video DACs can be found in many applications from set-top boxes to handheld devices, such as phones and MP3 players that play video.
The device operates from just 4,5 mA of bias current, and has a power-down state that consumes only 0,5 μA when the amplifier is not in use. It is ideal for systems with either two composite video signal inputs or outputs. It can be used as an input anti-aliasing filter before an ADC to remove high-frequency, non-image-forming noise from the signal before it is digitised.
As an output reconstruction filter, the ISL59118 can also be positioned after a DAC, where it smoothes out the digital output waveform that has been generated and removes glitches and noise. DACs are often not able to provide sufficient gain and output current to drive the video signal down a cable, or into a double terminated video load - a problem the device helps eliminate. It can also be used in applications where a video input is provided to record, as well as a video output to drive a cable to an external display.
The ISL59118 has a supply voltage range from 2,5 V to 3,6 V and is housed in an ultra-slim, micro-TQFN package.
