THS3122CDDA

The THS3122 and THS3125 are low-noise, highspeed current feedback amplifiers, with high output current drive. This makes them ideal for any application that requires low distortion over a wide frequency with heavy loads. The THS3122 and THS3125 can drive four serially-terminated video lines while maintaining a differential gain error less than 0.03%. The high output drive capability of the THS3122 and THS3125 enables the devices to drive 50-Ω loads with low distortion over a wide range of output voltages. The THS3122 and THS3125 operate from ±5-V to ±15-V supply voltages while drawing as little as 7.2-mA of supply current per channel. The THS3125 offers a low-power shutdown mode, reducing the supply current to only 370-μA. The THS3122 and THS3125 are packaged in SOIC, HSOP, and HTSSOP packages.
