DESCRIPTION
The THS3122/5 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
THS3122/5 can drive four serially terminated video
lines while maintaining a differential gain error less than
0.03%.
The high output drive capability of the THS3122/5
enables the devices to drive 50-
loads with low
distortion over a wide range of output voltages:
80 dBc THD at 2 VPP
75 dBc THD at 8 VPP
The THS3122/5 can operate from
±5 V to ±15 V supply
voltages while drawing as little as 7.2 mA of supply
current per channel. They offer a low power shutdown
mode, reducing the supply current to only 370
A. The
THS3122/5 are packaged in a standard SOIC, SOIC
PowerPAD
, and TSSOP PowerPAD packages.
