20 MHz filter amplifier in a 0.96 mm DSBGA
The Texas Instruments THS7320IYHCT is a three-channel filter amplifier in a 9-DSBGA package measuring 0.96x0.96 mm. It targets video and signal-conditioning applications where a compact, multi-channel active filter is needed. The -3 dB bandwidth of 20 MHz suits standard-definition and some high-definition video paths, while the 80 V/µs slew rate keeps large-signal edges clean. Outputs are rail-to-rail, which maximises headroom on a single 2.6 V to 5 V supply.
An 80 V/µs slew rate means the output can swing 4 V in 50 ns. For a 1 V peak-to-peak video signal at 5 MHz, that is plenty of margin to avoid slew-induced distortion. If you are driving an ADC input or a cable, the rail-to-rail output stage also helps keep the signal within the supply rails without external level shifting.
Three channels, one tiny footprint
Three independent amplifier circuits in a single 9-DSBGA package saves board area compared to three separate single-channel amplifiers. Each channel can deliver 65 mA of output current, enough to drive a 75 Ω video load or the input of a successive stage. Supply current per device is 3.5 mA typical, so total power for all three channels stays under 18 mW at 5 V.
Active, ROHS3, and the DSBGA reality
It is ROHS3 compliant. The 9-DSBGA package (0.96x0.96 mm) is a wafer-level chip-scale package; the solder balls are on the bottom with no leads. That means PCB layout needs a fine-pitch BGA fanout, and rework requires a hot-air station with a small nozzle and careful alignment.
