Description
The ZL40166 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). The wide bandwidth, high power output and low differential gain and phase figures make the ZL40166 ideally suited for a wide variety of video driver applications.

Application Notes
Data Sheet
The ZL40166 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 ZL40166 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 ZL40166 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 ZL40166 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.

Data Sheet Video transmitter and receiver for twisted wire pair.
ZL40166
Composite video signals can be transmitted down twisted pair cable, i.e. Ethernet (CAT 5), using a differential transmitter and receiver. The transmitter must be able to drive high currents into the low impedance twisted pair cable. For video, the amplifiers require flat gain and low phase-shift over the video signal band. To ensure this, the amplifiers will have 3dB bandwidths well in excess of this. The ZL40166 (dual amplifier) has all of these attributes. With reference to the differential video driver shown in Figure , the input coax is assumed to have a characteristic impedance of 75 Ohms, this is terminated with a parallel combination of 110 Ohms and the input impedance of amplifier IC1 (b) of 255 Ohms, giving 77 Ohms. Low values of feedback resistors are used around the op-amps to reduce phase-shift due to parasitic capacitors and to minimise the addition of noise. Baseband PAL or NTSC video signals generally have an amplitude of 2V pk-pk. A gain of two is used to ensure that the signal level at the end of the (terminated with 100 Ohms) differential pair will be the same as the input level, neglecting any losses due to the use of long cable lengths.

Figure 4 - Differential Video Driver The differential receiver is shown in Figure 5 has a 100 Ohm line termination resistor, followed by a differential amplifier. Long cables will tend to attenuate the signal with greater losses at the higher frequencies, so the second amplifier is used to equalise these losses. Initially the amplifier should be built without fitting components R1 and C1. Select the value of R2 to give the required gain at low frequency. Adjust the values of R1 and C1 to correct for the frequency dependant attenuation of the cable. To drive a coax cable the output of the amplifier is connected via a series matching 75 Ohm resistor, again this second (dual amplifier) ZL40166 provides the required power output for the restored 2Vpk-pk video signal.
