GENERAL DESCRIPTION

The AD829 is a low noise (1.7 nV/√Hz), high speed op amp with

custom compensation that provides the user with gains of 1 to 20

while maintaining a bandwidth >50 MHz. Its 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 bandwidth while requiring only 5 mA of current from

power supplies.

The external compensation pin of the AD829 gives it

exceptional versatility. For example, compensation can be

selected to optimize the bandwidth for a given load and power

supply voltage. As a gain-of-2 line driver, the −3 dB bandwidth

can be increased to 95 MHz at the expense of 1 dB of peaking.

Its output can also be clamped at its external compensation pin.

The AD829 exhibits excellent dc performance. It offers a minimum

open-loop gain of 30 V/mV into loads as low as 500 Ω, a low input

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.

This op amp is also useful in multichannel, high speed data

conversion where its fast (90 ns to 0.1%) settling time is important.

In such applications, the AD829 serves as an input buffer for 8-bit to

10-bit ADCs and as an output I/V converter for high speed DACs.

Operating as a traditional voltage feedback amplifier, the AD829

provides many of the advantages that a transimpedance amplifier

offer. A bandwidth >50 MHz can be maintained for a range of

gains through the replacement of 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 transimpedance

amplifiers. The inputs of the AD829 are symmetrical.

PRODUCT HIGHLIGHTS

The 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.

A differential phase error of 0.04 and a 0.02% differential

gain error, at the 3.58 MHz NTSC, 4.43 MHz PAL, and

SECAM color subcarrier frequencies, make the op amp 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.

The AD829 is available in PDIP, CERDIP, and small outline

packages. Chips and MIL-STD-883B parts are also available.

The 8-lead SOIC is available for the extended temperature

range (−40°C to +125°C).
