LF356-MIL - Texas Instruments

LF356-MIL JFET Input Operational Amplifier

The LF356-MIL device are the first monolithic JFET input operational amplifiers to incorporate wellmatched, 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 drif.

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 Input Offset Current: 3 pA
  – High Inp.
