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
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.
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 reverse terminated cable.
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.
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.
3. The AD827 can drive unlimited capacitive loads, while its
30 mA output current allows 50 and 75 reverse-
terminated loads to be driven.
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-lead plastic mini-DIP and cerdip,
20-lead LCC, and 16-lead SOIC packages. Chips and
MIL-STD-883B processing are also available.
