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
Ω 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.
