zl40162 data sheet 2 zarlink semiconductor inc. application notes 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 100 ? 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. 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. figure 3 - a non-inverting feedback amplifier example 100r rg rf1 rf2 12r5 12r5 rf rg
