  Low Power Op Amp: Low Power Filter, Headphone
  DriverВ Revisited
  Design Note 1041
  by Aaron Schultz
  Introduction
  A new family of op amps features industry leading
  speed versus supply current. The LTC6261/LTC6262/
  LTC6263 family (single, dual, quad) provides 30MHz
  at a low 240ВµA supply current, with 400ВµV maximum
  offset voltage and rail-to-rail input and output. In
  combination with 1.8V to 5.25V supply, these op
  amps enable applications requiring uncompromised
  performance with low power and low voltage.
  Active Filters
  This new set of op amps with high MHz-to-mA ratios
  provides an opportunity to look at filter circuits in a
  new light. The two filter examples discussed here
  display performance previously unachievable with
  such low power.
  Second Order Bessel Filter
  Ample bandwidth and low supply current enable
  deployment of active filters in portable and other low
  L, LT, LTC, LTM, Linear Technology and the Linear logo are registered …

  100mW delivered to reach 110dBSPL. With 32О©, the
  RMS current is 56mA and voltage 1.8V; with 120О©,
  29mA and 3.5V. Introduction
  A new family of op amps features industry leading
  speed versus supply current. The LTC6261/LTC6262/
  LTC6263 family (single, dual, quad) provides 30MHz
  at a low 240ВµA supply current, with 400ВµV maximum
  offset voltage and rail-to-rail input and output. In
  combination with 1.8V to 5.25V supply, these op
  amps enable applications requiring uncompromised
  performance with low power and low voltage. Given a 3.3V supply and the output of one LTC6261
  amplifier, there may not be sufficient drive capability to yield 100mW. However, the combination of
  two 180В° phased amplifiers is enough to provide
  the necessary drive to reach upwards of 100mW
  delivered power. Duplication of this bridge drive
  circuit enables power to both left and right sides. Bridge-Tied Differential Output Amplifier
  The low supply current at the bandwidth and noise
  performance allows for excellent fidelity at a fraction
  of the usual dissipation in portable audio equipment. …

  Low Power Op Amps: Only 20µA for 1.3MHz, 240µA for 30MHz &mdash LT Journal

  Low Power Op Amps: Only 20ВµA for 1.3MHz,
  240ВµA for 30MHz
  Aaron Schultz, Catherine Chang and Philip Karantzalis Our op amp family has expanded with industry-leading speed versus supply current.
  For super low 20ВµA supply current, the LTC6258/LTC6259/LTC6260 (single, dual,
  quad) provide 1.3MHz at a with 400ВµV maximum offset voltage and rail-to-rail
  input and output. The still-low 240ВµA of the LTC6261/LTC6262/ LTC6263 (single,
  dual, quad) provide 30MHz with 400ВµV maximum offset voltage and rail-to-rail
  input and output. In combination with 1.8V to 5.25V supply, these op amps enable
  applications requiring good performance with low power and low voltage.
  LOW NOISE REFERENCE This circuit takes advantage of the ability
  of the LTC6258 to drive large capacitive
  loads. Use of a large output capacitor
  bank attached to the LTC6258 enables
  significant bypassing of follow-on circuits
  that use the reference voltage. In total, 12 | July 2017 : LT Journal of Analog Innovation LT6656
