AD8565/AD8566/AD8567  
TOTAL HARMONIC DISTORTION + NOISE (THD+N)  
LCD PANEL APPLICATIONS  
The AD856x family features low total harmonic distortion.  
Figure 31 shows THD+N vs. frequency. The THD+N for the  
AD856x over the entire supply range is below 0.008%. When  
the device is powered from a 16 V supply, the THD+N stays  
below 0.003%. Figure 31 shows the AD8566 in a unity  
noninverting configuration.  
The AD856x amplifier is designed for LCD panel applications  
or applications where large capacitive load drive is required. It  
can instantaneously source/sink greater than 250 mA of current. At  
unity gain, it can drive 1 μF without compensation. This makes  
the AD856x ideal for LCD VCOM driver applications.  
To evaluate the performance of the AD856x family, a test circuit  
was developed to simulate the VCOM driver application for an  
LCD panel.

Figure 32 shows the test circuit. Series capacitors and resistors  
connected to the output of the op amp represent the load of the  
LCD panel. The 300 Ω and 3 kΩ feedback resistors are used to  
improve settling time. This test circuit simulates the worst-case  
scenario for a VCOM. It drives a represented load that is connected to  
a signal switched symmetrically around VCOM. Figure 33 shows a  
scope photo of the instantaneous output peak current capability  
of the AD856x family.

The AD856x family does not have internal short-circuit  
protection circuitry. As a precautionary measure, it is  
recommended not to short the output directly to the  
positive power supply or to ground.

It is not recommended to operate the AD856x with more than  
35 mA of continuous output current. The output current can be  
limited by placing a series resistor at the output of the amplifier
