2.2.2 THS6222RGTT

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

The unique architecture of the THS6222 uses minimal quiescent current by help of the BIAS pins, while achieving very high linearity. The amplifier has an adjustable current pin that sets the nominal current consumption along with 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 a receive mode.

The wide output swing of 57 VPP (100-Ω load) with 32-V power supplies, coupled with over 650-mA current drive (25 Ω) allows for wide dynamic range that keeps distortion minimal.
