10MHz
Low Gain Application Example for 1nV/Hz Amplifier
16Bit 10MHz ADC with 2V swing ½ LSB Noise=10uV 10uV@10MHz=3.4 nV/rt Hz RTO for ADC < 3.4 nV/rt Hz
AD8099 with 1V Input signal G=2 RTO Noise~ 3nV/rt Hz
Competition Low Gain Stable Amplifiers-
Slew Rate is too slow High Gain Stable Amplifiers-
RTO too high
AD8099
New Standard for High-Performance Packaging
New standard package--LFCSP
better thermals
smaller package
better parasitics
New standard pin-out is optimized for high speed
existing pin-out is 30+ years old
limits high-speed performance
better distortion
easier to lay out
bypass and feedback is optimized
New Standard LFCSP Pinout
Pin orientation is rotated by 1
Inductance coupling between
Vs and +IN is eliminated
source of second harmonic
distortion
Feedback from load is isolated
improves cap stability

AD8099: Overview of Major Benefits
Enables high-speed, 16-18 bit accurate signal processing provides extra room in the error budget
Allows for use of less expensive components
less calibration/trimming
Application flexibility with wide range of gain stability designer has the advantage of low noise at low gains with high slew rate
easy to reuse in other designs
Shorter time to market, less risk and lower cost easier to lay out
less thermal modeling
lower heat budget 3mA lower quiescent current than its leading competitors
