THS6222 - Texas Instruments

THS6222 Differential HPLC Line Driver

The THS6222 is a differential line-driver amplifier with a current-feedback architecture manufactured using Texas Instruments' proprietary, high-speed, silicon-germanium (SiGe) process. The device is targeted for use in broadband, high-speed, power line communications (HPLC) line driver applications that require high linearity when driving heavy line loads..
