  Fast Op Amps Operate Rail-to-Rail on 2.7V
  Design Note 241
  Glen Brisebois
  The new LTВ®1806 and LT1809 are fast operational
  amplifiers with rail-to-rail inputs and outputs. The
  LT1806 is optimized for low noise (3.5nV/в€љHz) and
  offset (100ОјV typical, 550ОјV max) and has a 325MHz
  gain bandwidth product. The LT1809 is optimized for
  low distortion (–90dBc to 5MHz) and has a 180MHz
  gain bandwidth product. Both amplifiers have 85mA
  output drive capability and are fully specified over
  commercial and industrial temperature ranges on 3V,
  5V and В±5V supplies.
  Parallel Composite Amplifier Achieves
  Low Distortion into Heavy Loads
  Achieving low distortion is difficult enough and driving
  heavy loads only makes the undertaking more difficult.
  Figure 1 shows a parallel composite topology where
  each amplifier is given a different responsibility. Amplifier U1 is configured in a standard gain of 2 to account
  for the eventual attenuation caused by the 50О© output
  divider. Amplifier U1 alone can drive the load, but its
  distortion figures would suffer. Therefore, amplifier
  U2 is added in a slightly higher gain and its output is …

  Rail-to-Rail I/O and 2.4V Operation Allow UltraFast Comparators to be Used on Low Voltage Supplies
  Design Note 248
  Glen Brisebois
  The new LTВ®1711 to LT1714 family of UltraFastв„ў
  comparators have full differential rail-to-rail inputs and
  outputs and operate down to 2.4V, allowing unfettered
  application on low supply voltages. The LT1711 (single)
  and LT1712 (dual) are specified at 4.5ns of propagation
  delay and 100MHz toggle frequency. The lower power
  LT1713 (single) and LT1714 (dual) are specified at 7ns
  of propagation delay and 65MHz toggle frequency. All
  of these comparators are fully equipped to support
  multiple supply applications and have Latch Enable
  (LE) pins and complementary outputs like the popular
  LT1016, LT1116, LT1671 and LT1394. They are available in MSOP and SSOP packages, fully specified
  over commercial and industrial temperature ranges
  on 2.7V, 5V and В±5V supplies.
  Simultaneous Full Duplex 75Mbaud Interface
  with Only Two Wires
  The circuit of Figure 1 shows a simple, fully bidirectional, differential 2-wire interface that gives good
  results to 75Mbaud, using the lower power LT1714.
  Eye diagrams under conditions of unidirectional and
  bidirectional communication are shown in Figures 2 …

  DESIGN FEATURES New UltraFast Comparators: Rail-toRail Inputs and 2.4V Operation Allow
  Use on Low Supplies
  by Glen Brisebois
  Introduction
  The new LT1711 family of UltraFast
  comparators has fully differential railto-rail inputs and outputs and
  operates on supplies as low as 2.4V,
  allowing unfettered application on low
  voltages. The LT1711 (single) and
  LT1712 (dual) are specified at 4.5ns
  of propagation delay and 100MHz
  toggle frequency. The low power
  LT1713 (single) and LT1714 (dual)
  are specified at 7ns of propagation
  delay and 65MHz toggle frequency.
  All of these comparators are fully
  equipped to support multiple-supply
  applications, and have latch-enable
  pins and complementary outputs like
  the popular LT1016, LT1671 and
  LT1394. They are available in MSOP
  and SSOP packages, fully specified
  over commercial and industrial temperature ranges on 2.7V, 5V and В±5V …
