LF356N/NOPB Operational amplifier, 1-fold, 12 V/µs, 5 MHz, DIP-8

LF356 JFET Input Operational Amplifiers

Description: The LFx5x devices 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.

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 - Common Features - Low Input Bias Current: 30 pA - Low Input Offset Current: 3 pA - High Input Impedance: 1012 O - Low Input Noise Current: 0.01 pA/vHz - High Common-Mode Rejection Ratio: 100 dB - Large DC Voltage Gain: 106 dB - Uncommon Features - Extremely Fast Settling Time to 0.01%: 1.5 µs for the LFx56 - Fast Slew Rate: 12 V/µs for the LFx56 - Wide Gain Bandwidth: 5 MHz for the LFx56 - Low Input Noise Voltage: 12 nV/vHz for the LFx56

Applications - Precision High-Speed Integrators - Fast D/A and A/D Converters - High Impedance Buffers - Wideband, Low Noise, Low Drift Amplifiers - Logarithmic Amplifiers - Photocell Amplifiers - Sample and Hold Circuits
