LF357 Description
www.DataSheet4U.com LF155/LF156/LF256/LF257/LF355/LF356/LF357 JFET Input Operational Amplifiers December 2001 LF155/LF156/LF256/LF257/LF355/LF356/L.
These are the first monolithic JFET input operational amplifiers to incorporate well matched, high voltage JFETs on the same chip with standard bipola.
LF357 Features
* n Low input bias current: 30pA n Low Input Offset Current: 3pA n High input impedance: 1012Ω n Low input noise current: n High common-mode rejection ratio: n Large dc voltage gain: 106 dB
100 dB
Features
Advantages n Replace expensive hybrid and module FET op amps n Rugged JFETs allow blow-out fre
LF357 Applications
* using either high or low source impedance
* very low 1/f corner n Offset adjust does not degrade drift or common-mode rejection as in most monolithic amplifiers n New output stage allows use of large capacitive loads (5,000 pF) without stability problems n Internal compensation and large dif
