What this chip does — video reconstruction filtering with differential drive
The ADA4433-1BCPZ-R7: Its 9.9 MHz -3 dB bandwidth is a good match for standard-definition composite video (NTSC/PAL) and similar analog video signals, where you need to pass the active video content while knocking down out-of-band DAC artifacts and clock noise. The differential output lets you drive balanced lines directly — think twisted-pair video or the input of a differential receiver — without an extra single-ended-to-differential stage. Output drive capability is 29 mA per channel, enough to source a standard 75 Ω load with headroom. Quiescent supply current is 13.2 mA, which is modest for a video-path part.
