AD8018 - xDSL Line Drive Amplifier

Description

The AD8018 is intended for use in single-supply (5 V) xDSL modems where high-output current and low distortion are essential to achieve maximum reach.

The dual high-speed amplifiers are capable of driving low distortion signals to within 0.5 V of the power supply rail.

Features

  • Ideal xDSL Line Drive Amplifier for USB, PCMCIA, or PCI-Based Customer Premise Equipment (CPE). The AD8018 provides maximum reach on 5 V supply, driving 16 dBm of power into a back-terminated, transformer-coupled 100 ⍀ while maintaining.
  • 82 dBc of out-of-band SFDR. Rail-to-Rail Output Voltage and High Output Current Drive 400 mA Output Current into Differential Load of 10 ⍀ @ 8 V p-p Low Single-Tone Distortion.
  • 86 dBc Worst Harmonic, 6 V p-p into Differential 10 ⍀ @ 100 kHz Low N.
