PRODUCT DE SCRIPT ION
T he AD829 is a low noise (1.7 nV/
√
Hz
), high speed op amp
with custom compensation that provides the user with gains
from
±
1 to
±
20 while maintaining a bandwidth greater than
50 MHz. T he AD829’s 0.04
°
differential phase and 0.02% dif-
ferential gain performance at 3.58 MHz and 4.43 MHz, driving
reverse-terminated 50
or 75
cables, makes it ideally suited
for professional video applications. T he AD829 achieves its
230 V/
μ
s uncompensated slew rate and 750 MHz gain band-
width product while requiring only 5 mA of current from the
power supplies.
T he AD829’s external compensation pin gives it exceptional
versatility. For example, compensation can be selected to opti-
mize the bandwidth for a given load and power supply voltage.
As a gain-of-two line driver, the –3 dB bandwidth can be in-
creased to 95 MHz at the expense of 1 dB of peaking. In addi-
tion, the AD829’s output can also be clamped at its external
compensation pin.
T he AD829 has excellent dc performance. It offers a minimum
open-loop gain of 30 V/mV into loads as low as 500
, low in-
put voltage noise of 1.7 nV/
√
Hz
, and a low input offset voltage
of 1 mV maximum. Common-mode rejection and power supply
rejection ratios are both 120 dB.
T he AD829 is also useful in multichannel, high speed data con-
version where its fast (90 ns to 0.1%) settling time is of impor-
tance. In such applications, the AD829 serves as an input buffer
for 8-to-10-bit A/D converters and as an output I/V converter
for high speed D/A converters.
T he AD829 provides many of the same advantages that a trans-
impedance amplifier offers, while operating as a traditional volt-
age feedback amplifier. A bandwidth greater than 50 MHz can
be maintained for a range of gains by changing the external
compensation capacitor. T he AD829 and the transimpedance
amplifier are both unity gain stable and provide similar voltage
noise performance (1.7 nV/
√
Hz
). However, the current noise of
the AD829 (1.5 pA/
√
Hz
) is less than 10% of the noise of trans-
impedance amps. Furthermore, the inputs of the AD829 are
symmetrical.
PRODUCT HIGHLIGHT S
1. Input voltage noise of 2 nV/
√
Hz
, current noise of 1.5 pA/
√
Hz
and 50 MHz bandwidth, for gains of 1 to 20, make the
AD829 an ideal preamp.
2. Differential phase error of 0.04
°
and a 0.02% differential
gain error, at the 3.58 MHz NT SC and 4.43 MHz PAL and
SECAM color subcarrier frequencies, make it an outstanding
video performer for driving reverse-terminated 50
and
75
cables to
±
1 V (at their terminated end).
3. T he AD829 can drive heavy capacitive loads.
4. Performance is fully specified for operation from
±
5 V to
±
15 V supplies.
5. Available in plastic, cerdip, and small outline packages.
Chips and MIL-ST D-883B parts are also available.
