Overview

2 differential DSL channels comprising current feedback, high output current amplifiers with integrated feedback resistors plus biasing network
Ideal for use as ADSL/ADSL2+ dual-channel central office (CO) line drivers
Low power consumption using Class H technology
- Single 12.5 V supply operation
  - 20.4 dBm line power, 1:1 transformer
- Less than 600 mW per channel total power dissipation while driving 20.4 dBm (includes 110 mW line power)
- Less than 275 mW per channel total power dissipation while driving 14.5 dBm (including line power)
High output voltage and current drive
- 43.4 V differential output voltage swing
Low distortion
- −65 dBc typical multitone power ratio (MTPR) at 20.4 dBm, 26 kHz to 2.2 MHz
Low cost protection components enable ITU-T-K20 and GR-1089 compliance

The ADLD8403 comprises two differential, 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 can deliver 20.4 dBm to a line while compensating for losses due to hybrid insertion and back termination resistors. The ADLD8403 uses the Analog Devices, Inc., second generation Adaptive Linear Power™ (Class H) architecture to achieve unprecedented power efficiency using a single power supply. Additional functionality allows the shutdown of pumps for enhanced power savings for line powers of less than 14.5 dBm. This functionality yields the smallest printed circuit board (PCB) footprint and lowest total cost of ownership.

The low power consumption, high output current, high output voltage swing, and robust thermal packaging enable the ADLD8403 to be the CO line driver in ADSL and other xDSL systems.

The ADLD8403 is available in a 4 mm × 4 mm, 20-lead LFCSP.
