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.
The AD8099 features external compensation, which lets the
user set the gain bandwidth product. External compensation
allows gains from +2 to +10 with minimal trade-off in band-
width. The AD8099 also features an extremely high slew rate of
1350 V/μs, giving the designer flexibility to use the entire
dynamic range without trading off bandwidth or distortion.
The AD8099 settles to 0.1% in 18 ns and recovers from
overdrive in 50 ns.
The AD8099 drives 100 Ω loads at breakthrough performance
levels with only 15 mA of supply current. With the wide supply
voltage range (5 V to 12 V), low offset voltage (0.1 mV typ),
wide bandwidth (700 MHz for G = +2), and a GBWP up to
3.8 GHz, the AD8099 is designed to work in a wide variety of
applications.

The AD8099 is available in a 3 mm × 3 mm lead frame chip
scale package (LFCSP) with a new pinout that is specifically
optimized for high performance, high speed amplifiers. The
new LFCSP package and pinout enable the breakthrough
performance that previously was not achievable with amplifiers.
The AD8099 is rated to work over the extended industrial
temperature range, −40°C to +125°C.
