The LF347 Quad JFET-Input Operational Amplifier IC 3 MHz DIP-14 is a high-performance, general-purpose operational amplifier integrating four independent JFET-input op-amp channels on a single monolithic IC. It delivers a wide gain-bandwidth product of approximately 3 MHz and a high slew rate of around 13 V/µs while maintaining low supply current consumption, making it suitable for high-speed analog signal processing applications.
Features:
- Quad JFET-input operational amplifiers.
- Very low input bias current (50pA typical).
- High gain-bandwidth product (4MHz typical).
- High slew rate (13V/µs typical).
- Wide supply voltage range (±5V to ±18V).
- Low supply current (7mA typical).
- Internally compensated for unity-gain operation.
