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.
The unique architecture of the THS6222 uses minimal quiescent current while achieving very high linearity. The amplifier has an adjustable current pin (IADJ) that sets the nominal current consumption along with the multiple bias modes that allow for enhanced power savings where the full performance of the amplifier is not required. Shutdown bias mode provides further power savings during receive mode in time division multiplexed (TDM) systems while maintaining high output impedance. The integrated midsupply common-mode buffer eliminates external components, reducing system cost and board space.
The wide output swing of 57 VPP (100 Ω load) with32-V power supplies, coupled with over 650 mA current drive (25 Ω load), allows for wide dynamic range that keeps distortion minimal.
The THS6222 is available in a 24-pin VQFN package with exposed thermal pad and is specified for operation from –40°C to +85°C ambient temperature.
