PRODUCT DESCRIPTION

The AD827 is a dual version of Analog Devices’ industry-

standard AD847 op amp. Like the AD847, it provides high

speed, low power performance at low cost. The AD827 achieves

a 300 V/µs slew rate and 50 MHz unity-gain bandwidth while

consuming only 100 mW when operating from ±5 volt power

supplies. Performance is specified for operation using ±5 V to

±15 V power supplies.

The AD827 offers an open-loop gain of 3,500 V/V into 500 Ω

loads. It also features a low input voltage noise of 15 nV/√Hz,

and a low input offset voltage of 2 mV maximum. Common-

mode rejection ratio is a minimum of 80 dB. Power supply

rejection ratio is maintained at better than 20 dB with input

frequencies as high as 1 MHz, thus minimizing noise

feedthrough from switching power supplies.

APPLICATION HIGHLIGHTS

1. Performance is fully specified for operation using ±5 V to

±15 V supplies.

2. A 0.04% differential gain and 0.19° differential phase error at

the 4.4 MHz color subcarrier frequency, together with its low

cost, make it ideal for many video applications.

The AD827 is also ideal for use in demanding video applica-

tions, driving coaxial cables with less than 0.04% differential

gain and 0.19° differential phase errors for 643 mV p-p into a

75 Ω reverse terminated cable.

3. The AD827 can drive unlimited capacitive loads, while its

30 mA output current allows 50 Ω and 75 Ω reverse-

terminated loads to be driven.

The AD827 is also useful in multichannel, high speed data

conversion systems where its fast (120 ns to 0.1%) settling time

is of importance. In such applications, the AD827 serves as an

input buffer for 8-bit to 10-bit A/D converters and as an output

amplifier for high speed D/A converters.

4. The AD827’s 50 MHz unity-gain bandwidth makes it an

ideal candidate for multistage active filters.

5. The AD827 is available in 8-pin plastic mini-DIP and cerdip,

20-pin LCC, and 16-pin SOIC packages. Chips and MIL-

STD-883B processing are also available.
