Texas Instruments  THS6212IRHFT

The THS6212 is a differential line-driver amplifier with a current-feedbackarchitecture. 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 to30 MHz.

The unique architecture of the THS6212 uses minimal quiescent current and still achievesvery high linearity. Differential distortion under full bias conditions is –93 dBc at 1 MHz andreduces to only –73 dBc at 10 MHz. Fixed multiple bias settings of the amplifiers allow forenhanced power savings for line lengths where the full performance of the amplifier is notrequired. To allow for even more flexibility and power savings, an adjustable current pin (IADJ) isavailable 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 dynamicheadroom that keeps distortion minimal.

The THS6212 is available in a 24-pin VQFN package and a 17 bond pad wafer salepackage.
