LF257 Datasheet

Features and benefits

Advantages n Replace expensive hybrid and module FET op amps n Rugged JFETs allow blow-out free handling compared with MOSFET input devices n Excellent for low noise appl.

Application

using either high or low source impedance — very low 1/f corner n Offset adjust does not de.

Description

These are the first monolithic JFET input operational amplifiers to incorporate well matched, high voltage JFETs on the same chip with standard bipolar transistors (BI-FET™ Technology). These amplifiers feature low input bias and offset currents/low .
