  C-Load Op Amps Conquer Instabilities – Design Note 107
  Kevin R. Hoskins
  Introduction
  Linear Technology Corporation has taken advantage of
  advances in process technology and circuit innovations
  to create a series of C-Loadв„ў operational amplifiers that
  are tolerant of capacitive loading, including the ultimate,
  amplifiers that remain stable driving any capacitive load.
  This series of amplifiers has a bandwidth that ranges from
  160kHz to 140MHz. These amplifiers are appropriate for
  a wide range of applications from coaxial cable drivers to
  analog-to-digital converter (ADC) input buffer/amplifiers.
  Driving ADCs
  Most contemporary ADCs incorporate a sample-and-hold
  (S/H). A typical S/H circuit is shown in Figure 1. The hold
  capacitor’s (C1) size varies with the ADC’s resolution but
  is generally in the range of 5pF to 20pF, 10pF to 30pF and
  10pF to 50pF for 8-, 10-and 12-bit ADCs, respectively. gracefully and accurately drive capacitive loads, such as
  Linear Technology’s C-Load line of monolithic amplifiers.
  Table 1 lists Linear Technology’s unconditionally stable
  voltage feedback C-Load amplifiers. Table 2 lists other
  voltage feedback C-Load amplifiers that are stable with
  loads up to 10,000pF. …

  Micropower 4-and 8-Channel, 12-Bit ADCs
  Save Power and Space – Design Note 153
  Kevin R. Hoskins
  Introduction
  Data acquisition applications that require low power
  dissipation fall into two general areas: products that
  must use power very efficiently, such as battery-powered
  portable test equipment, and remotely located data logging equipment. To help meet these requirements, Linear
  Technology has introduced the LTCВ®1594 and LTC1598.
  Micropower ADCs in Small Packages
  The LTC1594/LTC1594L and LTC1598/LTC1598L are
  micropower 12-bit ADCs that feature a 4-and 8-channel multiplexer, respectively. To cover different system
  supply voltages, the LTC1594 and LTC1598 operate on
  5V and the LTC1594L and LTC1598L operate on 3V. The
  LTC1594L and the LTC1598L are tested to operate on
  supplies as low as 2.7V and sample at a maximum of
  10.5ksps. The LTC1594 and LTC1598 have a maximum
  sample rate of 16.8ksps. At full conversion rate, the
  LTC1594/LTC1598 and LTC1594L/LTC1598L typically
  draw 320ОјA and 160ОјA, respectively. At 1ksps these
  converters typically draw 20ОјA. The LTC1594/LTC1594L
  are available in a 16-pin SO package and the LTC1598/
  LTC1598L are available in a 24-pin SSOP package. …
