The OPA2607 provides a high output voltage swing and low distortion required for low turns ratio ADSL upstream driver applications. Operating on a 12V supply, the OPA2607 consumes a low 8.0mA/channel quiescent current to deliver a very high 250mA peak output current. Guaranteed output current of 180mA supports even the most demanding ADSL CPE requirements with low harmonic distortion. Differential driver applications will deliver < 75dBc 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.
