Four-channel filter amp — what the 9.5 MHz bandwidth buys you
The Texas Instruments THS7372IPWR packs four independent filter amplifiers in a 14-TSSOP package, each with a rail-to-rail output stage. The 9.5 MHz -3dB bandwidth is sized for composite video (CVBS) and standard-definition analog video paths — it passes the luminance and chrominance content cleanly while rolling off out-of-band noise. Each channel can deliver 90 mA, enough to drive a 75-ohm cable directly or feed a downstream ADC input without a separate buffer.
Rail-to-rail output means the signal swing reaches the supply rails — useful when the ADC reference is tied to the same supply and you want every millivolt of headroom. The 24.5 mA supply current for all four channels is modest; thermal dissipation in the 14-TSSOP stays manageable even at 5 V.
