THS3122 的说明
The THS3122 and THS3125 are low-noise, high-speed 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:
- –80-dBc THD at 2 VPP
- –75-dBc THD at 8 VPP
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.
