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
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 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).
3. The 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-STD-883B parts are also available.
