Its function is to amplify the analog signal from the DSL transceiver onto the twisted-pair line, driving the line impedance with enough voltage swing and current to meet the loop-length and data-rate targets. The part operates from a 12.6 V to 15.4 V supply rail, drawing 26.1 mA typical supply current. That 1.37 W power dissipation budget means the exposed pad on the 20-VFQFN package must be soldered to a copper plane on the PCB to keep the junction temperature within the -40°C to 125°C operating range. ## Supply rail and thermal design notes The supply voltage tolerance is tighter than many general-purpose op-amps: 12.6 V to 15.4 V, so the rail needs a regulated supply — a 12 V rail from a DC-DC converter will be too low, and an unregulated wall-wart will drift out of spec under load. Budget a linear regulator or a tight-output DC-DC set to 13.5 V nominal. The 1.37 W power dissipation at 26.1 mA supply current is the thermal design ceiling. The 20-VFQFN package with exposed pad (4x4 mm) relies on the PCB copper pour to sink heat. A layout engineer should allocate a thermal via array under the pad and connect it to a ground plane on the inner layer; without that, the junction temperature will exceed 125°C at the top end of the ambient range. ## Lifecycle and sourcing reality For a BOM line, this means no forced redesign cycle — the part is available for new designs and ongoing production.
