Texas Instruments THS6226AIRHBT

The THS6226A is a dual-port, class H, current-feedback architecture, differential line driver amplifier system ideal for xDSL systems. The device is targeted for use in very-high-bit-rate digital subscriber line 2 (VDSL2) line driver systems that enable native DTM signals while supporting greater than +20.5-dBm line power (up to 8.5 MHz) with good linearity, supporting the G.993.2 VDSL2 8b profile. The device is also fast enough to support central-office transmissions of +14.5-dBm line power up to 30 MHz.

The unique architecture of the device allows quiescent current to be minimal while still achieving very high linearity. Differential distortion, under full bias conditions, is –91 dBc at 1 MHz and reduces to only –75 dBc at 5 MHz. Fixed multiple bias settings of the amplifiers offer 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 on all profiles, quiescent current is digitally adjustable from 7.6 mA to 23 mA with a bias current step of 1.0 mA. For systems where additional power savings while not transmitting are desired, the device can be used in its line termination mode to maintain impedance matching.

The wide output swing on +12-V power supplies, coupled with excellent current drive, allows for wide dynamic headroom, keeping distortion minimal. The device is available in a VQFN-32 PowerPAD™ package.
