The THS6092/3 is a high-speed line driver ideal for driving signals from the remote terminal to the central office in asymmetrical digital subscriber line (ADSL) applications. It can operate from a single +12-V supply voltage while drawing only 7.3 mA of supply current per channel. It offers low -72 dBc total harmonic distortion driving a 25-load (2 Vpp). The THS6092/3 offers a high 18.4-Vpp differential output swing across a 50-load from a single +12-V supply. The THS6093 features a low-power shutdown mode, consuming only 300 uA quiescent current per channel. The THS6092/3 is packaged in a standard SOIC, SOIC PowerPAD™, and TSSOP PowerPAD™ package.

The THS6132 is a Class-G current feedback differential line driver ideal for full rate ADSL DMT systems. Its extremely low power consumption of 600 mW or lower is ideal for ADSL systems that must achieve high densities in ADSL central office rack applications. The unique patent pending architecture of the THS6132 allows the quiescent current to be much lower than existing line drivers while still achieving very high linearity. In addition, the multiple bias settings of the amplifiers allow for even lower power consumption for line lengths where the full performance of the amplifier is not required. The output voltage swing has been vastly improved over first generation Glass-G amplifiers and allows the use of lower power supply voltages that help conserve power. For maximum flexibility, the THS6132 can be configured in classical Class-AB mode requiring only as few as one power supply.

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. Distortion at these low-power levels is good with -83-dBc THD at 1 MHz with the low bias mode of 4.2 mA/port. Fixed and variable multiple-bias settings of the amplifiers allows for enhanced power savings for line lengths where the full performance of the amplifier is not required. The wide output swing of 44-VPPdifferentially with ±12-V power supplies coupled with over 415-mA current drive allow for wide dynamic range, keeping distortion minimized. With a low 3-nV/√Hzvoltage noise coupled with a low 5.9-pA/√Hzinverting current noise, the THS6184 increases the sensitivity of the receive signals allowing for better margins and reach.

The THS6204 is a dual-port, current-feedback architecture, differential line driver amplifier system ideal for xDSL systems. The device is targeted for use in VDSL2 (very-high-bit-rate digital subscriber line 2) line driver systems that enable greater than +20.5dBm line power up to 8.5MHz with good linearity supporting the G.993.2 VDSL2 8b profile. It is also fast enough to support central-office transmission of +14.5dBm line power up to 18.1MHz—Profile 30a. The unique architecture of the THS6204 allows quiescent current to be minimal while still achieving very high linearity. Differential distortion, under full bias conditions, is -89dBc at 1MHz and reduces to only -73dBc at 10MHz. Fixed multiple bias settings of the amplifiers allows 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 IADJpin is available to further lower the bias currents. The wide output swing of 43.2VPP(100differentially) with ±12V power supplies, coupled with over 425mA current drive (25), allows for wide dynamic headroom, keeping distortion minimal. The THS6204 is available in a QFN-24 or a TSSOP-24 PowerPAD™ package. The THS6204 is a dual-port, current-feedback architecture, differential line driver amplifier system ideal for xDSL systems.
