Ultralow Distortion, High Speed, 0.95 nV/√Hz Voltage Noise Op Amp AD8099 Data Sheet FEATURES CONNECTION DIAGRAMS AD8099 Ultralow noise: 0.95 nV/√Hz, 2.6 pA/√Hz Ultralow distortion 2nd harmonic RL = 1 kΩ , G = +2 −92 dB at 10 MHz 3rd harmonic RL = 1 kΩ , G = +2 −105 dB at 10 MHz High speed Gain bandwidth product (GBWP): 3.8 GHz −3 dB bandwidth 700 MHz (G = +2) 550 MHz (G = +10) Slew rate 475 V/µs (G = +2) 1350 V/µs (G = +10) New pinout Custom external compensation, gain range –1, +2 to +10 Supply current: 15 mA Offset voltage: 0.5 mV max Wide supply voltage range: 5 V to 12 V GENERAL DESCRIPTION The AD8099 is an ultralow noise (0.95 nV/√Hz) and distortion (–92 dBc at 10 MHz) voltage feedback op amp, the combination of which makes 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. The Analog Devices, Inc., proprietary next generation extra fast complimentary bipolar (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 bandwidth. 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. Rev. E 8 +VS 6 CC +IN 4 5 –VS 04511-0-001 7 VOUT –IN 3 NOTES 1. SOLDER THE EXPOSED PADDLE TO THE GROUND PLANE.

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 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. –40 G = +2 V = 2V p-p –50 VOUT S = ±5V RL = 1kΩ –60 –70 –80 –90 –100 –110 –120 –130 0.1 SOLID LINE – SECOND HARMONIC DOTTED LINE – THIRD HARMONIC 1.0 FREQUENCY (MHz) 10.0 04511-A-013 Preamplifiers Receivers Instrumentation Filters Intermediate frequency (IF) and baseband amplifiers Analog-to-digital drivers Digital-to-analog converter (DAC) buffers Optical electronics DISABLE 1 FEEDDBACK 2 HARMONIC DISTORTION (dBc) APPLICATIONS TOP VIEW (Not to Scale) Figure 3.
