SNOSBH0D – MAY 2000 – REVISED NOVEMBER 2015
LFx5x JFET Input Operational Amplifiers
1 Features
•1 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
• Common Features – Low Input Bias Current: 30 pA – Low Inpu
