AD8392:  Low Power, High Output Current, Dual Channel ADSL/ADSL2+ Line Driver

Product Description

The AD8392 is comprised of four high output current, low power consumption, operational amplifiers. It is particularly well suited for the CO driver interface in digital subscriber line systems, such as ADSL and ADSL2+. The driver is capable of providing enough power to deliver 20.4 dBm to a line, while compensating for losses due to hybrid insertion and back termination resistors. In addition, the low distortion, fast slew rate, and high output current capability make the AD8392 ideal for many other applications, including medical instrumentation, DAC output drivers, and other high peak current circuits.

The AD8392 is available in two thermally enhanced packages, a 28-lead TSSOP/EP (AD8392ARE) and a 5 mm x 5 mm 32-lead LFCSP (AD8392ACP). Four bias modes are available via the use of two digital bits (PD1, PD0).

Features

  • Four current feedback, high current amplifiers
  • Ideal for use as ADSL/ADSL2+ dual-channel Central Office (CO) line drivers
  • Low power operation
    Power supply operation from ±5 V (+10 V) up to ±12 V (+24)
    Less than 3 mA/Amp quiescent supply current for full power ADSL/ADSL2+ CO applications (20.4 dBm line power, 5.5CF)
    Three active power modes plus shutdown
  • High output voltage and current drive
    400 mA peak output drive current
    44 V p-p differential output voltage
  • Low distortion
    -72 dBc @ 1 MHz second harmonic
    -82 dBc @ 1 MHz third harmonic
  • High speed: 900 V/µs differential slew rate
  • Additional functionality of AD8392ACP
    On-chip common-mode voltage generation
