  • Product introduction

The THS3122/5 is a low noise, high speed current feedback amplifier with high output current drive. This makes them ideal for any application that requires a wide range of frequencies with low distortion of heavy loads. The THS3122/5 can drive quad serial-terminated video lines while maintaining a differential gain error of less than 0.03%.

The high output THS3122/5 drive capability enables the device to drive a wide range of output voltages into low-distortion 50Ω loads:

  • - 80 - dBc total harmonic distortion at 2Vpeak
  • - 75 - dBc total harmonic distortion8Vpeak

The THS3122/5 can operate at ± 5 V to ± 15 V supply voltage while plotting supply currents as low as 7.2 per channel. The THS3125 provides a low power shutdown mode resulting in a supply current of only 370 μA.
