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.
rejection ratio is maintained at better than 20 dB with input frequencies as high as 1 MHz, thus minimizing noi feedthrough from switching power supplies.
The AD827 is also ideal for u in demanding video applica-tions, driving coaxial cables with less than 0.04% differential gain and 0.19° differential pha errors for 643 mV p-p into a 75 Ω rever terminated cable.
The AD827 is also uful in multichannel, high speed data conversion systems where its fast (120 ns to 0.1%) ttling time is of importance. In such applications, the AD827 rves 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 pha 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 Ω and 75 Ω rever-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-pin plastic mini-DIP and cerdip,20-pin LCC, and 16-pin SOIC packages. Chips and MIL-STD-883B processing are also available.

INPUT PROTECTION PRECAUTIONS
An input resistor (resistor R IN of Figure 21a) is recommended in circuits where the input common-mode voltage to the AD827may exceed (on a transient basis) the positive supply voltage.This resistor provides protection for the input transistors by limiting the maximum current that can be forced into their bas.
For high performance circuits, it is recommended that a cond resistor (R B in Figures 21a and 22a) be ud to reduce bias-current errors by matching the impedance at each input. This resistor reduces the error caud by offt voltages by more than
an order of magnitude.
