The AD827 is a dual version of Analog Devices’ industrystandard AD847 op amp. Like the AD847, it provides high speed, low power performance at low cost. The AD827 achieves a 300 V/ms 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 W loads. It also features a low input voltage noise of 15 nV/ÖHz, and a low input offset voltage of 2 mV maximum. Commonmode 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 applications, driving coaxial cables with less than 0.04% differential gain and 0.19° differential phase errors for 643 mV p-p into a 75 W 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.

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 W and 75 W reverseterminated 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.

1Offset voltage for the AD827 is guaranteed after power is applied and the device is fully warmed up. All other specifications are measured using high speed test equipment, approximately 1 second after power is applied.
2Full Power Bandwidth = Slew Rate/2 π VPEAK. 3Gain = +1, rising edge.
All min and max specifications are guaranteed.

NOTES
1Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only, and functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum ratings for extended periods may affect device reliability.
2Maximum internal power dissipation is specified so that TJ does not exceed +175°C at an ambient temperature of +25°C.
Thermal Characteristics:
Mini-DIP: θJA = 100°C/Watt; θJC = 33°C/ Watt Cerdip: θJA = 110°C/Watt; θJC = 30°C/Watt 16-Pin Small Outline Package: θJA = 100°C/Watt 20-Pin LCC: θJA = 150°C/Watt; θJC = 35°C/Watt
3Indefinite short circuit duration is only permissible as long as the absolute maximum power rating is not exceeded.
