Data Sheet Ultralow Power, Adaptive Linear Power, Dual-Port ADSL/ADSL2+ Line Driver ADLD8403 08848-001 FEATURES 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 APPLICATIONS ADSL/ADSL2+ CO line drivers INTERNAL SCHEMATIC VCC VCCP INPA VCOM_A INNA VCC 4kΩ 4kΩ AV = 13V/V VOPA VONA VEEP Figure 1. Channel A Internal Schematic GENERAL DESCRIPTION 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 generatio.
