PRODUCT DESCRIPTION

The 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. The AD829’s 0.04° differential phase and 0.02%
differential gain performance at 3.58 MHz and 4.43 MHz,
driving reverse-terminated 50 Ω or 75 Ω cables, makes it ideally
suited for professional video applications. The AD829 achieves
its 230 V/µs uncompensated slew rate and 750 MHz gain band-
width product while requiring only 5 mA of current from the
power supplies.
The 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.
The AD829 has excellent dc performance. It offers a minimum
open-loop gain of 30 V/mV into loads as low as 500 Ω, low
input voltage noise of 1.7 nV/√Hz, and a low input offset volt-
age of 1 mV maximum. Common-mode rejection and power
supply rejection ratios are both 120 dB.
The AD829 is also useful in multichannel, high speed data
conversion where its fast (90 ns to 0.1%) settling time is of
importance. In such applications, the AD829 serves as an input
buffer for 8-to-10-bit A/D converters and as an output I/V con-
verter for high speed D/A converters.
The AD829 provides many of the same advantages that a trans-
impedance amplifier offers, while operating as a traditional
voltage feedback amplifier. A bandwidth greater than 50 MHz
can be maintained for a range of gains by changing the external
compensation capacitor. The 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 HIGHLIGHTS
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.Differential phase error of 0.04° and a 0.02% differential
gain error, at the 3.58 MHz NTSC and 4.43 MHz PAL and
SECAM color subcarrier frequencies, make it an outstanding
video performer for driving reverse-terminated 50 Ω and
75 Ω cables to ±1 V (at their terminated end).The AD829 can drive heavy capacitive loads.Performance is fully specified for operation from ±5 V to
±15 V supplies.Available in plastic, cerdip, and small outline packages.
Chips and MIL-STD-883B parts are also available.

NOTESStresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only and functional operation of
the device at these or any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.Maximum internal power dissipation is specified so that TJ does not exceed
+175°C at an ambient temperature of +25°C.
Thermal characteristics:
8-lead plastic package: θJA = 100°C/watt (derate at 8.7 mW/°C)
8-lead cerdip package: θJA = 110°C/watt (derate at 8.7 mW/°C)
20-lead LCC package: θJA = 150°C/watt
8-lead small outline package: θJA = 155°C/watt (derate at 6 mW/°C).If the differential voltage exceeds 6 volts, external series protection resistors should
be added to limit the input current.
ORDERING GUIDE
ESD SUSCEPTIBILITY

ESD (electrostatic discharge) sensitive device. Electrostatic
charges as high as 4000 volts, which readily accumulate on the
human body and on test equipment, can discharge without
detection. Although the AD829 features proprietary ESD pro-
tection circuitry, permanent damage may still occur on these
devices if they are subjected to high energy electrostatic dis-
charges. Therefore, proper ESD precautions are recommended
to avoid any performance degradation or loss of functionality.
