GENERAL DESCRIPTION

The AD8099 is an ultralow noise (0.95 nV/√Hz) and distortion (–92 dBc @10 MHz) voltage feedback op amp, the combination of which make it ideal for 16- and 18-bit systems. The AD8099 features a new, highly linear, low noise input stage that increases the full power bandwidth (FPBW) at low gains with high slew rates. ADI’s proprietary next generation XFCB process enables such high performance amplifiers with relatively low power.
