  The LT1167: Single Resistor Sets the Gain of the Best
  Instrumentation Amplifier – Design Note 182
  Alexander Strong and Kevin R. Hoskins
  Introduction
  Linear Technology’s next generation LT®1167 instrumentation amplifier uses a single resistor to set gains
  from 1 to 10,000. The single gain-set resistor eliminates
  expensive resistor arrays and improves VOS and CMRR
  performance. Careful attention to circuit design and
  layout, combined with laser trimming, greatly enhances
  the CMRR, PSRR, gain error and nonlinearity, maximizing application versatility. The CMRR is guaranteed to
  be greater than 90dB when the LT1167’s gain is set at
  1. Total input offset voltage (VOS) is less than 60ОјV at a
  gain of 10. For gains in the range of 1 to 100, gain error
  is less than 0.05%, making the gain-set resistor tolerance the dominant source of gain error. The LT1167’s
  gain nonlinearity is unsurpassed when compared to
  other monolithic solutions. It is specified at less than
  40ppm when operating at a gain of 1000 while driving
  a 2kО© load. The LT1167 is so robust that it can drive
  600Ω loads without a significant linearity penalty. These
  parametric improvements result in an overall gain error
  that remains unchanged over the entire input common
  mode range and is not degraded by supply perturbations
  or varying load conditions. The LT1167 can operate over …

  DESIGN FEATURES High Speed SO-8 12-Bit ADCs
  Run on 5V or 3V
  by Ricky Chow and Teo Yang Long
  Introduction
  Advancing the leading edge of high
  speed, low power 12-bit serial ADCs
  in SO-8, LTC introduces the LTC1401
  and LTC1404. The LTC1401 is a single
  3V supply, 200ksps 12-bit ADC. The
  LTC1404 is a pin-to-pin compatible
  upgrade of the existing LTC1400. It
  samples at 600ksps on either single
  5V or В±5V supplies. Both of these
  devices are small in size but big in
  features. They achieve speeds that
  are far ahead of the pack. Once again,
  LTC has rewritten the record for the
  highest throughput per square area
  of board space of any 12-bit ADC on
  the market. Both devices satisfy
  tomorrow’s digitally based signal-processing requirements while achieving
  a minimum footprint. Full ADC Features
  in an SO-8 Package …
