GENERAL DESCRIPTION
The AD8027/AD80281 are high speed amplifiers with rail-to-rail input and output that operate on low supply voltages and are optimized for high performance and wide dynamic signal range. The AD8027/AD8028 have low noise (4.3 nV/√Hz, 1.6 pA/√Hz) and low distortion (120 dBc at 1 MHz). In applications that use a fraction of, or the entire input dynamic range and require low distortion, the AD8027/AD8028 are ideal choices.

FEATURES
High speed
  190 MHz, –3 dB bandwidth (G = +1)
  100 V/μs slew rate
Low distortion
  120 dBc @ 1 MHz SFDR
  80 dBc @ 5 MHz SFDR
Selectable input crossover threshold
Low noise
  4.3 nV/√Hz
  1.6 pA/√Hz
Low offset voltage: 900 μV max
Low power: 6.5 mA/amplifier supply current
Power-down mode
No phase reversal: VIN > |VS| + 200 mV
Wide supply range: 2.7 V to 12 V
Small packaging: SOIC-8, SOT-23-6, MSOP-10

APPLICATIONS
Filters
ADC drivers
Level shifting
Buffering
Professional video
Low voltage instrumentation
