LCC E Package PRODUCT DESCRIPTION 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 s 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 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 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 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 lead plastic mini DIP and cerdip 20 lead LCC and 16 lead SOIC packages Chips and MIL STD 883B processing are also available REV C Information furnished by Analog Devices is believed to be
