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 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 bandwidth while

requiring only 5 mA of current from power supplies.

The AD829’s external compensation pin 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-two line driver, the –3 dB bandwidth can be increased

to 95 MHz at the expense of 1 dB of peaking. The AD829’s

output can also be clamped at its external compensation pin.

The AD829 exhibits excellent dc performance. It offers a mini-

mum 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

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 impor-

tant. In such applications, the AD829 serves as an input buffer

for 8-bit to 10-bit A/D converters and as an output I/V con-

verter for high speed DACs.

Load

Operating as a traditional voltage feedback amplifier, the AD829

provides many of the advantages a transimpedance amplifier

offers. A bandwidth greater than 50 MHz can be maintained for

a range of gains through the replacement of the external com-

pensation 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 amps. The inputs of the AD829 are symmetrical.

PRODUCT HIGHLIGHTS

1. Input voltage noise of 2 nV/√Hz, current noise of 1.5 pA/√Hz,

2. Differential phase error of 0.04° and a 0.02% differential

3. The AD829 can drive heavy capacitive loads.

4. Performance is fully specified for operation from ± 5 V to

5. The AD829 is available in plastic, CERDIP, and small outline

and 50 MHz bandwidth, for gains of 1 to 20, make the AD829

an ideal preamp.

gain error, at the 3.58 MHz NTSC and 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).
