PRODUCT DESCRIPTION
The AD827 is a dual version of Analog Devices’ industrystandard AD847 op amp. Like the AD847, it provides high
speed, low power performance at low cost. The AD827 achieves
a 300 V/µs slew rate and 50 MHz unity-gain bandwidth while
consuming only 100 mW when operating from ± 5 volt power
supplies. Performance is specified for operation using ± 5 V to
± 15 V power supplies.
The AD827 offers an open-loop gain of 3,500 V/V into 500 Ω
loads. It also features a low input voltage noise of 15 nV/√Hz,
and a low input offset voltage of 2 mV maximum. Commonmode rejection ratio is a minimum of 80 dB. Power supply
rejection ratio is maintained at better than 20 dB with input
frequencies as high as 1 MHz, thus minimizing noise
feedthrough from switching power supplies.
The AD827 is also ideal for use in demanding video applications, driving coaxial cables with less than 0.04% differential
gain and 0.19° differential phase errors for 643 mV p-p into a
75 Ω reverse terminated cable.
The AD827 is also useful in multichannel, high speed data
conversion systems where its fast (120 ns to 0.1%) settling time
is of importance. In such applications, the AD827 serves as an
input buffer for 8-bit to 10-bit A/D converters and as an output
amplifier for high speed D/A converters.
APPLICATION HIGHLIGHTS
1. Performance is fully specified for operation using ± 5 V to
± 15 V supplies.
2. A 0.04% differential gain and 0.19° differential phase error at
the 4.4 MHz color subcarrier frequency, together with its low
cost, make it ideal for many video applications.
3. The AD827 can drive unlimited capacitive loads, while its
30 mA output current allows 50 Ω and 75 Ω reverseterminated loads to be driven.
4. The AD827’s 50 MHz unity-gain bandwidth makes it an
ideal candidate for multistage active filters.
5. The AD827 is available in 8-lead plastic mini-DIP and cerdip,
20-lead LCC, and 16-lead SOIC packages. Chips and
MIL-STD-883B processing are also available.

INPUT PROTECTION PRECAUTIONS
An input resistor (resistor RIN of Figure 21a) is recommended in
circuits where the input common-mode voltage to the AD827
may exceed (on a transient basis) the positive supply voltage.
This resistor provides protection for the input transistors by
limiting the maximum current that can be forced into their bases.
For high performance circuits, it is recommended that a second
resistor (RB in Figures 21a and 22a) be used to reduce biascurrent errors by matching the impedance at each input. This
resistor reduces the error caused by offset voltages by more than
an order of magnitude.

The termination resistor, RT, (when equal to the cable’s
characteristic impedance) minimizes reflections from the far end
of the cable. While operating from ± 5 V supplies, the AD827
maintains a typical slew rate of 200 V/µs, which means it can
drive a ± 1 V, 30 MHz signal into a terminated cable.

A back-termination resistor (RBT, also equal to the characteristic
impedance of the cable) may be placed between the AD827
output and the cable input, in order to damp any reflected
signals caused by a mismatch between RT and the cable’s
characteristic impedance. This will result in a flatter frequency
response, although this requires that the op amp supply ± 2 V to
the output in order to achieve a ± 1 V swing at resistor RT.

AD827
A TWO-CHIP VOLTAGE-CONTROLLED AMPLIFIER
(VCA) WITH EXPONENTIAL RESPONSE
Voltage-controlled amplifiers are often used as building blocks
in automatic gain control systems. Figure 25 shows a two-chip
VCA built using the AD827 and the AD539, a dual, currentoutput multiplier. As configured, the circuit has its two
between the CH1 output and Z1, the other between the CH1
output and W1. Likewise, in the CH2 multiplier, one of the
feedback resistors is connected between CH2 and Z2 and the
other is connected between CH2 and Z2. In Figure 25, Z1 and
W1 are tied together, as are Z2 and W2, providing a 3 kΩ
feedback resistor for the op amp. The 2 pF capacitors connected
between the AD539’s W1 and CH1 and W2 and CH2 pins are
in parallel with the feedback resistors and thus reduce peaking
in the VCA’s frequency response. Increasing the values of C3
and C4 can further reduce the peaking at the expense of
reduced bandwidth. The 1.25 mA full-scale output current of
the AD539 and the 3 kΩ feedback resistor set the full-scale
output voltage of each multiplier at 3.25 V p-p.
Current limiting in the AD827 (typically 30 mA) limits the output voltage in this application to about 3 V p-p across a 100 Ω
load. Driving a 50 Ω reverse-terminated load divides this value
by two, limiting the maximum signal delivered to a 50 Ω load to
about 1.5 V p-p, which suffices for video signal levels. The
dynamic range of this circuit is approximately 55 dB and is
primarily limited by feedthrough at low input levels and by the
maximum output voltage at high levels.
Figure 25. A Wide Range Voltage-Controlled
Amplifier Circuit
multipliers connected in series. They could also be placed in
parallel with an increase in bandwidth and a reduction in gain.
The gain of the circuit is controlled by VX, which can range
from 0 to 3 V dc. Measurements show that this circuit easily
supplies 2 V p-p into a 100 Ω load while operating from ± 5 V
supplies. The overall bandwidth of the circuit is approximately
7 MHz with 0.5 dB of peaking.
Each half of the AD827 serves as an I/V converter and converts
the output current of one of the two multipliers in the AD539
into an output voltage. Each of the AD539’s two multipliers
contains two internal 6 kΩ feedback resistors; one is connected
Guidelines for Grounding and Bypassing
When designing practical high frequency circuits using the AD827,
some special precautions are in order. Both short interconnection
leads and a large ground plane are needed whenever possible to
provide low resistance, low inductance circuit paths. One should
remember to minimize the effects of capacitive coupling
between circuits. Furthermore, IC sockets should be avoided.
Feedback resistors should be of a low enough value that the
time constant formed with stray circuit capacitances at the
amplifier summing junction will not limit circuit performance.
As a rule of thumb, use feedback resistor values that are less
than 5 kΩ. If a larger resistor value is necessary, a small (<10 pF)
feedback capacitor in parallel with the feedback resistor may be
used. The use of 0.1 µF ceramic disc capacitors is recommended
for bypassing the op amp’s power supply leads.
