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 30 MHz.
The unique architecture of the THS6212 uses minimal quiescent current and still achieves very high linearity. Differential distortion under full bias conditions is –86-dBc at 1 MHz and reduces to only –71 dBc at 10 MHz. Fixed multiple bias settings 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 49 VPP (100-Ω differential load) with 28-V power supplies, coupled with over a 650-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.
