AD8510/AD8512/AD8513  
A typical value for Rd is 1000 MΩ. Because Rd >> R2, the  
circuit behavior is not impacted by the effect of the junction  
resistance. The maximum signal bandwidth is  
I-V CONVERSION APPLICATIONS  
Photodiode Circuits  
Common applications for I-V conversion include photodiode  
circuits where the amplifier is used to convert a current emitted  
by a diode placed at the positive input terminal into an output  
voltage.  
ft  
fMAX  
=
2πR2Ct  
where ft is the unity gain frequency of the amplifier.  
The AD8510/AD8512/AD8513’s low input bias current, wide  
bandwidth, and low noise make them each an excellent choice  
for various photodiode applications, including fax machines,  
fiber optic controls, motion sensors, and bar code readers.  
Cf can be calculated by  
Ct  
Cf =  
2πR2 ft  
The circuit shown in Figure 53 uses a silicon diode with zero  
bias voltage. This is known as a photovoltaic mode; this  
configuration limits the overall noise and is suitable for  
instrumentation applications.  
where ft is the unity gain frequency of the op amp, and it achieves  
a phase margin, φM, of approximately 45°.  
A higher phase margin can be obtained by increasing the value  
of Cf. Setting Cf to twice the previous value yields approximately  
φM = 65° and a maximal flat frequency response, but it reduces the  
maximum signal bandwidth by 50%.

R2  
Using the previous parameters with a Cf ≈ 1 pF, the signal  
bandwidth is approximately 2.6 MHz.

Signal Transmission Applications

One popular signal transmission method uses pulse-width  
modulation. High data rates may require a fast comparator  
rather than an op amp. However, the need for sharp, undistorted  
signals may favor using a linear amplifier.

VCC  
The AD8510/AD8512/AD8513 make excellent voltage  
comparators. In addition to a high slew rate, the AD8510/  
AD8512/AD8513 have a very fast saturation recovery time. In  
the absence of feedback, the amplifiers are in open-loop mode  
(very high gain). In this mode of operation, they spend much of  
their time in saturation.  
Figure 53. Equivalent Preamplifier Photodiode Circuit  
A larger signal bandwidth can be attained at the expense of  
additional output noise. The total input capacitance (Ct)  
consists of the sum of the diode capacitance (typically 3 pF to  
4 pF) and the amplifier’s input capacitance (12 pF), which  
includes external parasitic capacitance. Ct creates a pole in the  
frequency response that can lead to an unstable system. To  
ensure stability and optimize the bandwidth of the signal, a  
capacitor is placed in the feedback loop of the circuit shown in  
Figure 53. It creates a zero and yields a bandwidth whose corner  
frequency is 1/(2π(R2Cf)).  
The circuit shown in Figure 54 was used to compare two signals  
of different frequencies, namely a 100 Hz sine wave and a 1 kHz  
triangular wave. Figure 55 shows a scope plot of the resulting  
output waveforms. A pull-up resistor (typically 5 kΩ) can be  
connected from the output to VCC if the output voltage needs to  
reach the positive rail. The trade-off is that power consumption  
is higher.  
The value of R2 can be determined by the ratio

V1  
For example, if ID is 100 μA and a 10 V output voltage is desired,  
R2 should be 100 kΩ. Rd (see Figure 53) is a junction resistance  
that drops typically by a factor of 2 for every 10°C increase in  
temperature.
