  16-Bit, 333ksps ADC Achieves 90dB SINAD, –100dB THD
  and No Missing Codes – Design Note 177
  Marco Pan and Kevin R. Hoskins
  Fastest 16-Bit Sampling ADC
  Linear Technology’s recently introduced LTC®1604 is
  the fastest, highest performance 16-bit sampling ADC
  on the market. This device samples at 333ksps and
  delivers excellent DC and AC performance. The LTC1604
  operates on В± 5V supplies and typically dissipates just
  220mW. It has a fully differential input sample-andhold and an onboard reference. Two power shutdown
  modes, NAP and SLEEP, reduce power consumption to
  7mW and 10ОјW, respectively. At 333ksps, this 16-bit
  device not only offers performance superior to that
  of the best hybrids, but does so with low power, the
  smallest size, an easy-to-use parallel interface and the
  lower cost of a monolithic part. It is available in a tiny
  36-pin SSOP package. Some of the key features of this
  new device include: 333ksps throughput 16 bits with no missing codes and В± 2LSB INL Low power dissipation and power shutdown (10ОјW
  in SLEEP mode) Excellent AC performance: 90dB SINAD and –100dB
  THD Small 36-pin SSOP package
  These features of the LTC1604 can simplify, improve
  and lower the cost of current data acquisition systems
  and open up new applications that were not previously …

  DESIGN FEATURES Dual Operational Amplifier Combines
  16-Bit Precision with High Speed
  by Kris Lokere
  Introduction
  The LT1469 is a dual operational
  amplifier that has been optimized for
  accuracy and speed in 16-bit systems. The amplifier settles in just
  900ns to 150ВµV for a 10V step. The
  LT1469 also features the excellent
  DC specifications required for 16-bit
  designs. Input offset voltage is 125ВµV
  maximum, input bias current is 10nA
  maximum for the inverting input and
  minimum DC gain is 300V/mV. The
  LT1469 specifications are summarized in Table 1.
  This article presents two applications of the LT1469 in 16-bit
  data-conversion systems. The first
  application is with a fast currentoutput digital-to-analog converter
  (DAC), such as the LTC1597. The
  dual LT1469 amplifier allows this
  DAC to operate in bipolar, 4-quadrant multiplying mode. The second
  application illustrates the use of this
  dual amplifier as a buffer for a differential analog-to-digital converter …

  DESIGN FEATURES LT1468: An Operational Amplifier
  for Fast, 16-Bit Systems
  by George Feliz
  Introduction
  The LT1468 is a single operational
  amplifier that has been optimized for
  accuracy and speed in 16-bit systems. Operating from В±15V supplies,
  the LT1468 in a gain of –1 configuration will settle in 900ns to 150µ V for
  a 10V step. The LT1468 also features
  the excellent DC specifications
  required for 16-bit designs. Input offset voltage is 75Вµ V max, input bias
  current is 10nA maximum for the
  inverting input and 40nA maximum
  for the noninverting input and DC
  gain is 1V/ВµV minimum. The LT1468
  specifications are summarized in
  Table 1. Two key applications that
  illustrate its use are current-to-voltage (I/V) conversion following a fast,
  16-bit current output digital-to-analog converter (DAC), such as LTC1597
  (Figure 1), and buffering the input of
  an analog-to-digital converter (ADC),
  such as the 333ksps LTC1604 (Figure 2). Both applications will be
  discussed in detail to highlight the …
