It features low noise and low distortion acpanied by a high output current which makes it ideally suited for the application as an x DSL line driver. The dual opamp can be connected as a differential line driver delivering signals up to 18.8Vpp swing into a 25Ω load, fully supporting the peak upstream power levels for upstream full-rate ADSL (Asymmetrical Digital Subscriber Line). - - - - - Applications - - - ADSL PCI modem cards x DSL external modem Line Driver Out_1 8 V+ 7 Out_2 In_n_1 2 In_p_1 3 6 In_n_2 V- 4 5 In_p_2 Figure 1 - Functional Block Diagram and Pin Connection Application Notes Data Sheet The ZL40162 is a high speed, high output current, dual operational amplifier with a high slew rate and low distortion. The device uses conventional voltage feedback for ease of use and more flexibility. These characteristics make the ZL40162 ideal for applications where driving low impedances of 25 to 100Ω such as x DSL and active filters. The figure below shows a typical ADSL application utilising a 1:2 transformer, the feedback path provides a Gain = +2. 12R5 Rf1 Rg Rf2 12R5...
