  Introduction
  The LTВ®1462/LT1464 duals and the LT1463/LT1465
  quads are the first micropower op amps to offer
  picoampere input bias currents and unity-gain stability
  when driving capacitive loads. For each amplifier, the
  LT1462/LT1463 consume only 28ВµA of supply current;
  the faster LT1464/LT1465, just 145ВµA. Low supply
  current and operation specified at В±5V supplies make
  these amplifiers appropriate for portable low power applications. The LT1462/3/4/5 family is especially suited
  for piezo transducer conditioning, strain gauge weight
  scales, very low droop track-and-holds, wide dynamic
  range photodiode amplifiers and other applications that
  benefit from pA input bias current. The LT1462/3/4/5
  family also exhibits very low noise current, important to
  circuits such as low frequency filters. These op amps allow high value resistors to be used with easily obtainable,
  low value precision capacitors to set a filter’s frequency
  characteristics without compromising noise performance. Driving Large Capacitive Loads
  Though the LT1462/3/4/5 consume very small amounts
  of supply current, they can easily drive 10nF loads while …
