The THS6212 is a differential line-driver amplifier with a current-feedback
architecture. The device is targeted for use in broadband, wideband power line communications (PLC)
line driver applications and is fast enough to support transmissions of 14.5-dBm line power up to
The unique architecture of the THS6212 uses minimal quiescent current and still achieves
very high linearity. Differential distortion under full bias conditions is –93 dBc at 1 MHz and
reduces to only –73 dBc at 10 MHz. Fixed multiple bias settings of the amplifiers allow for
enhanced power savings for line lengths where the full performance of the amplifier is not
required. To allow for even more flexibility and power savings, an adjustable current pin (IADJ) is
available to further lower the bias currents.
The wide output swing of 43.2 VPP (100-Ω differential load) with
±12-V power supplies, coupled with over a 416-mA current drive (25-Ω load), allows for wide dynamic
headroom that keeps distortion minimal.
The THS6212 is available in a 24-pin VQFN package.
