The AD8028-KGD-CHIP1 is a high speed amplifier with rail-to- rail input and output that operates on low supply voltages and is optimized for high performance and wide dynamic signal range. The AD8028-KGD-CHIP has low noise (4.3 nV/√Hz, 1.6 pA/√Hz) and low distortion (120 dBc at 1 MHz). In applications that use a fraction of or the entire input dynamic range and require low distortion, the AD8028-KGD-CHIP is an ideal choice. 1Protected by U.S. patent numbers 6,486,737B1; 6,518,842B1
