Operating on a ±12V supply, the OPA2607 consumes a low 8.0m A/channel quiescent current to deliver a very high 250m A peak output current. Guaranteed output current of 180m A supports even the most demanding ADSL CPE requirements with low harmonic distortion. Differential driver applications will deliver < - 75d Bc distortion at the peak upstream power levels of full rate ADSL. Using a differential driver design, as shown below, the OPA2607 can deliver a high 38Vp-p voltage swing into a 1:0.8 step-down transformer to meet the ADSL CPE upstream power requirements. This low turns ratio actually provides a step up to the much weaker downstream signal arriving on the line side of this transformer, extending the DSL modem’s reach. Power control features are included in the SO-14 package version to allow system power to be minimized. Two logic control lines allow four quiescent power settings. These include full power, power cutback for short loops, idle state for no signal transmission but line match maintenance, and shutdown for power off with a high impedance output. An additional I ADJ pin allows the maximum supply current to be adjusted ±25% from the nominal value. Connecting this pin to +VCC will increase the full power quiescent to 20m A, increasing the peak output current available, while connecting this pin to - VCC will decrease the full power quiescent to 12m A where a lower peak output current is required. The digital control lines continue to scale the total quiescent current from these new maximum levels in the same proportional...
