THS6184 - LOW-POWER DIFFERENTIAL xDSL LINE DRIVER AMPLIFIERS

General Description

The THS6184 is a dual-port, low-power current feedback differential line driver amplifier system ideal for xDSL systems.

Its extremely low-power dissipation is ideal for ADSL, ADSL2, ADSL2+, and ADSL2++ systems that must achieve high densities in ADSL central office applications by combining two ports, or four amplifiers, into one package.

The unique architecture of the THS6184 allows the trimmed quiescent current to be much lower than existing line drivers while still achieving high linearity.
