GENERAL DESCRIPTION
The AD8510/AD8512/AD8513 are single-, dual-, and quadprecision JFET amplifiers that feature low offset voltage, input
bias current, input voltage noise, and input current noise.
The combination of low offsets, low noise, and very low input
bias currents makes these amplifiers especially suitable for high
impedance sensor amplification and precise current measurements
using shunts. The combination of dc precision, low noise, and
fast settling time results in superior accuracy in medical
instruments, electronic measurement, and automated test
equipment. Unlike many competitive amplifiers, the AD8510/
AD8512/AD8513 maintain their fast settling performance even
with substantial capacitive loads. Unlike many older JFET
amplifiers, the AD8510/AD8512/AD8513 do not suffer from
output phase reversal when input voltages exceed the maximum
common-mode voltage range.
Fast slew rate and great stability with capacitive loads make the
AD8510/AD8512/AD8513 a perfect fit for high performance
filters. Low input bias currents, low offset, and low noise result
in a wide dynamic range of photodiode amplifier circuits. Low
noise and distortion, high output current, and excellent speed
make the AD8510/AD8512/AD8513 great choices for audio
applications.
The AD8510/AD8512 are both available in 8-lead narrow SOIC_N
and 8-lead MSOP packages. MSOP-packaged parts are only
available in tape and reel. The AD8513 is available in 14-lead
SOIC_N and TSSOP packages.
The AD8510/AD8512/AD8513 are specified over the −40°C to
+125°C extended industrial temperature range.

Phase reversal is a change of polarity in the transfer function of
the amplifier. This can occur when the voltage applied at the
input of an amplifier exceeds the maximum common-mode
voltage.
The low input current noise and input bias current of the
AD8510/AD8512/AD8513 make them the ideal amplifiers for
circuits with substantial input source resistance. Input offset
voltage increases by less than 15 nV per 500 Ω of source
resistance at room temperature. The total noise density of the
circuit is
Phase reversal can cause permanent damage to the device and
can result in system lockups. The AD8510/AD8512/AD8513 do
not exhibit phase reversal when input voltages are beyond the

The AD8510/AD8512/AD8513 have low THD and excellent gain
linearity, making these amplifiers great choices for precision
circuits with high closed-loop gain and for audio application
circuits. Figure 42 shows that the AD8510/AD8512/AD8513 have
approximately 0.0005% of total distortion when configured in
positive unity gain (the worst case) and driving a 100 kΩ load.
Note that the previous analysis is valid for frequencies larger
than 150 Hz and assumes flat noise above 10 kHz. For lower
frequencies, flicker noise (1/f) must be considered.

Settling time is the time it takes the output of the amplifier to
reach and remain within a percentage of its final value after a
pulse is applied at the input. The AD8510/AD8512/AD8513
settle to within 0.01% in less than 900 ns with a step of 0 V to
10 V in unity gain. This makes each of these parts an excellent
choice as a buffer at the output of DACs whose settling time is
typically less than 1 μs.

CAPACITIVE LOAD DRIVE
The AD8510/AD8512/AD8513 are unconditionally stable at all
gains in inverting and noninverting configurations. Each device
is capable of driving a capacitive load of up to 1000 pF without
oscillation in unity gain using the worst-case configuration.
However, as with most amplifiers, driving larger capacitive
loads in a unity gain configuration may cause excessive
overshoot and ringing, or even oscillation. A simple snubber
network significantly reduces the amount of overshoot and
ringing. The advantage of this configuration is that the output
swing of the amplifier is not reduced, because RS is outside the
feedback loop.

of more than 52°.
When the snubber circuit is used, the overshoot is reduced from
55% to less than 3% with the same load capacitance. Ringing is
virtually eliminated, as shown in Figure 47.

PRECISION RECTIFIERS
VOLTAGE (1V/DIV)
Rectifying circuits are used in a multitude of applications. One
of the most popular uses is in the design of regulated power
supplies, where a rectifier circuit is used to convert an input
sinusoid to a unipolar output voltage.
02729-046
However, there are some potential problems with amplifiers
used in this manner. When the input voltage (VIN) is negative,
the output is zero, and the magnitude of VIN is doubled at the
inputs of the op amp. If this voltage exceeds the power supply
voltage, it may permanently damage some amplifiers. In addition,
the op amp must come out of saturation when VIN is negative.
This delays the output signal because the amplifier requires
time to enter its linear region.
TIME (1ms/DIV)
Although the AD8510/AD8512/AD8513 have a very fast
overdrive recovery time, which makes them great choices for the
rectification of transient signals, the symmetry of the positive
and negative recovery times is also important to keep the output
signal undistorted.

Figure 50 shows the test circuit of the rectifier. The first stage of
the circuit is a half-wave rectifier. When the sine wave applied at
the input is positive, the output follows the input response.
During the negative cycle of the input, the output tries to swing
negative to follow the input, but the power supply restrains it to
zero. In a similar fashion, the second stage is a follower during
the positive cycle of the sine wave and an inverter during the
negative cycle.

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.
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.
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.
Cf
R2
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
f MAX =
ft
2πR2Ct
where ft is the unity gain frequency of the amplifier.
Cf can be calculated by
Cf =
Ct
2πR2 ft
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%.
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.

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 value of R2 can be determined by the ratio
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.
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.

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.

The AD8510 single has two additional active terminals that are
not present on the AD8512 dual or AD8513 quad parts. These
pins are labeled “null” and are used for fine adjustment of the
input offset voltage. Although the guaranteed maximum offset
voltage at room temperature is 400 μV and over the −40°C to
+125°C range is 800 mV maximum, this offset voltage can be
reduced by adding a potentiometer to the null pins as shown in
Figure 58. With the 20 kΩ potentiometer shown, the adjustment
range is approximately ±3.5 mV. The potentiometer parallels
low value resistors in the drain circuit of the JFET differential
input pair and allows unbalancing of the drain currents to
change the offset voltage. If offset adjustment is not required,
these pins should be left unconnected.

Crosstalk, also known as channel separation, is a measure of
signal feedthrough from one channel to another on the same

than −90 dB for frequencies up to 10 kHz and of better than
−50 dB for frequencies up to 10 MHz. Figure 57 shows the

Caution should be used when adding adjusting potentiometers to
any op amp with this capability for several reasons. First, there is
gain from these nodes to the output; therefore, capacitive coupling
from noisy traces to these nodes will inject noise into the signal
path. Second, the temperature coefficient of the potentiometer
will not match the temperature coefficient of the internal resistors,
so the offset voltage drift with temperature will be slightly affected.
Third, this provision is for adjusting the offset voltage of the
op amp, not for adjusting the offset of the overall system. Although
it is tempting to decrease the value of the potentiometer to attain
more range, this will adversely affect the dc and ac parameters.
