Tomorrow's high speed xDSL Internet access technology will require drivers and receivers capable of transmitting high data rates over low impedance telephone lines with minimal distortion. The THS6002 from Texas Instruments is the answer.

The THS6002 is composed of four high-speed, current feedback operational amplifiers. Two of the four amplifiers are optimized as drivers, offering 480-mA typical output current, 1000-V/µs slew rate, and 140-MHz bandwidth. The other two amplifiers are configured as receivers and offer the same high performance at a lower output drive. Each amplifier also features individual power supply connections to minimize crosstalk between the devices.

This device operates over a wide range of supply voltages, ranging from ± 5 V to ± 15 V, and can drive up to a 40-V peak-to-peak differential output voltage. This makes the THS6002 well suited for a variety of xDSL applications including ADSL and HDSL at the central office and remote terminals.

The THS6002 is available in a small, surface mount, thermally enhanced SOIC 20-pin PowerPAD package. For more information on this innovative new package, see the PowerPAD application note at http://www.ti.com/sc/docs/psheets/abstract/apps/slma002.htm.

Applications:

  • ADSL
  • HDSL
  • Video Distribution
