Overview
The THS6222IRHFR is a differential line-driver amplifier manufactured by Texas Instruments. It is designed using Texas Instruments' proprietary high-speed silicon-germanium (SiGe) process. This device is targeted for use in broadband, high-speed power line communications (HPLC) line driver applications, requiring high linearity when driving heavy line loads. The THS6222IRHFR features a current-feedback architecture, which minimizes quiescent current while achieving high linearity. It includes an integrated midsupply common-mode buffer, reducing the need for external components and thus lowering system cost and board space.
