AD8565/AD8566/AD8567  
APPLICATIONS  
Theory of Operation  
The benefit of this type of input stage is low bias current. The  
input bias current is the sum of base currents of Q4–Q5 and  
Q6–Q8 over the range from (VNEG + 1 V) to (VPOS – 1 V). Outside  
of this range, input bias current is dominated by the sum of base  
current of Q10–Q11 for input signals close to VNEG and of Q6–Q8  
(Q10–Q11) for signal close to VPOS. From this type of design,  
the input bias current of AD856x not only exhibits different  
amplitude, but also exhibits different polarities. Figure 2 provides  
the characteristics of the input bias current versus common-mode  
voltage. It is important to keep in mind that the source impedances  
driving the AD856x inputs are balanced for optimum dc and ac  
performance.  
The AD856x family is designed to drive large capacitive loads in  
LCD applications. It has high output current drive, rail-to-rail  
input/output operation and is powered from a single 16 V supply.  
It is also intended for other applications where low distortion and  
high output current drive are needed.  
Figure 1 illustrates a simplified equivalent circuit for the AD856x.  
The rail-to-rail bipolar input stage is composed of two PNP  
differential pairs, Q4–Q5 and Q10–Q11, operating in series with  
diode protection networks, D1–D2. Diode network D1–D2  
serves as protection against large transients for Q4–Q5, to  
accommodate rail-to-rail input swing. D5–D6 protect Q10–Q11  
against zenering. In normal operation, Q10–Q11 are off and their  
input stage is buffered from the operational amplifier inputs by  
Q6–D3 and Q8–D4. Operation of the input stage is best understood  
as a function of applied common-mode voltage: When the inputs  
of the AD856x are biased midway between the supplies, the  
differential signal path gain is controlled by resistive loads (Via R9,  
R10) Q4–Q5. As the input common-mode level is reduced toward  
the negative supply (VNEG or GND), the input transistor current  
sources, I1 and I2, are forced into saturation, thereby forcing the  
Q6–D3 and Q8–D4 networks into cutoff; However, Q4–Q5 remain  
active, providing input stage gain. Inversely, when common-mode  
input voltage is increased toward the positive supply, Q4–Q5 are  
driven into cutoff, Q3 is driven into saturation, and Q4 becomes  
active, providing bias to the Q10–Q11 differential pair. The point  
at which Q10–Q11 differential pair becomes active is approximately  
equal to (VPOS – 1 V).

In order to achieve rail-to-rail output performance, the AD856x  
design uses a complementary common-source (or gmRL) output.  
This configuration allows output voltages to approach the power  
supply rails, particularly if the output transistors are allowed to  
enter the triode region on extremes of signal swing which are  
limited by VGS, the transistor sizes, and output load current.  
Also, this type of output stage exhibits voltage gain in an open-loop  
gain configuration. The amount of gain depends on the total  
load resistance at the output of the AD856x.

Input Overvoltage Protection  
Q4  
As with any semiconductor device, whenever the input exceeds  
either supply voltages, attention needs to be paid to the input  
overvoltage characteristics. As an overvoltage occurs, the amplifier  
could be damaged, depending on the voltage level and the magnitude  
of the fault current. When the input voltage exceeds either supply  
by more than 0.6 V, internal pn junctions will allow current to  
flow from the input to the supplies.

This input current is not inherently damaging to the device as  
long as it is limited to 5 mA or less. If a condition exists using  
the AD856x where the input exceeds the supply more than 0.6 V,  
a series external resistor should be added. The size of the resistor  
can be calculated by using the maximum overvoltage divided by  
5 mA. This resistance should be placed in series with either input  
exposed to an overvoltage.
