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/ 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
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. 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
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.
