LF356 - JFET Input Operational Amplifiers
Datasheet Packaging Samples & Pricing Reliability Design Tools Models Application Notes Knowledge Base

Features
Advantages
Replace expensive hybrid and module FET op amps
Rugged JFETs allow blow-out free handling compared with MOSFET input devices
Excellent for low noise applications using either high or low source impedance-very low 1/f corner
Offset adjust does not degrade drift or common-mode rejection as in most monolithic amplifiers
New output stage allows use of large capacitive loads (5,000 pF) without stability problems
Internal compensation and large differential input voltage capability

General 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). More...

General 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 offset voltage and offset voltage drift, coupled with offset adjust which does not degrade drift or common-mode rejection. The devices are also designed for high slew rate, wide bandwidth, extremely fast settling time, low voltage and current noise and a low 1/f noise corner.

Reliability Metrics


Part Number Process EFR Reject EFR Sample Size PPM LTA Rejects LTA Device Hours FITS MTTF (Hours)
LF356MBIFET0128750010650004302196657
LF356MXBIFET0128750010650004302196657
LF356NBIFET0128750010650004302196657

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
