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. Common- mode rejection ratio is a minimum of 80 dB. Power supply APPLICATION HIGHLIGHTS rejection ratio is maintained at better than 20 dB with input 1.
