  3. ADI’s Amplifier Architectures

  4. Expanding Our Lead through Process and Design • Proprietary Process provides better performance with lower power • Next Generation XFCB1.5 • JFET & Bipolar Transistors • 8 GHz NPN • 5 GHz PNP • Ability to Introduce New Incredible Designs • Fast FET™ Input Amps • Low Noise and Distortion @ Low Power • Low Power with High Performance

  5. AD8099 vs. Competition

  6. AD8099 vs. Competition

  7. 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 16 Bit ADC 10MHz AD8099

  8. 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

  9. - + –V S 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 NC Disable 8 1 Old Pinout –IN +VS 2 7 - +IN VOUT 6 + 3 –VS CC 4 5 +V 8 1 Disable S New Pinout Feedback 2 7 V OUT –IN 6 3 CC +IN 5 4

  10. 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
