Description
The ZL40162 is a low cost voltage feedback opamp
capable of driving signals to within 1V of the power
supply rails. 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 25
load, fully supporting the peak upstream power levels
for upstream full-rate ADSL (Asymmetrical Digital
Subscriber Line).

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.

Absolute Maximum Ratings -
(See Note 1)
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate
conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed
specifications and the test conditions, see the Electrical Characteristics.
Note 2: Human body model, 1.5k
in series with 100pF. Machine model, 200 in series with 100pF.
Note 3: 1.25kV between the pairs of +INA, -INA and +INB, -INB pins only. 4kV between supply pins, OUTA or OUTB pins and any
input pin.
Note 4: +/-100mA applied to input and output pins to force the device to go into "latch-up". The device passes this test to JEDEC spec
17.
Note 5: Positive and Negative supply transient testing increases the supplies by 20% for 100ms.
