It features low noise and low distortion accompanied by a high output current which makes it ideally suited for the application as an xDSL 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).

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 xDSL 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 100R Rf2 12R5 Figure 2 - A Typical ADSL Application A class AB output stage allows the ZL40162 to deliver high currents to low impedance loads with low distortion while consuming low quiescent current. Note: the high ESD immunity figure of 4kV may mean that in some designs fewer additional EMC protection components are needed thus reducing total system costs. The ZL40162 is not limited to ADSL applications and can be used as a general purpose opamp configured with either inverting or non-inverting feedback. The figure below shows non-inverting feedback arrangement that has typically been used to obtain the data sheet specifications.
