1 / 12 page CONNECTION DIAGRAMS a High Speed, Low Power Dual Op Amp AD827 FEATURES High Speed 50 MHz Unity Gain Stable Operation 300 V/ms Slew Rate 120 ns Settling Time Drives Unlimited Capacitive Loads Excellent Video Performance 0.04% Differential Gain @ 4.4 MHz 0.198 Differential Phase @ 4.4 MHz Good DC Performance 2 mV max Input Offset Voltage 15 mV/8C Input Offset Voltage Drift Available in Tape and Reel in Accordance with EIA-481A Standard Low Power Only 10 mA Total Supply Current for Both Amplifiers 5 V to 15 V Supplies 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. 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. 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 Ω and 75 Ω 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. 8-Lead Plastic (N) and Cerdip (Q) Packages 16-Lead Small Outline (R) Package 20-Lead LCC (E) Package REV.
