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

In such applications, the AD827 serves as an ideal candidate for multistage active filters. input buffer for 8-bit to 10-bit A/D converters and as an output amplifier for high speed D/A converters. 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. REV.
