LT1462/LT1463/LT1464/LT1465: Micropower Dual and Quad JFET

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 filterвЂ™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 …
