The JFET front end delivers a typical input bias current of 30 pA, which keeps the voltage error negligible when driving high-impedance sources like photodiode transimpedance stages or precision integrators. The 5 MHz gain-bandwidth product and 12V/µs slew rate are enough for audio-frequency signal conditioning and moderate-speed data acquisition front ends. ## Supply rail — 30 V to 40 V span The supply voltage range runs from 30 V minimum to 40 V maximum. That is a ±15 V to ±20 V split-supply capability, which is higher than most modern low-voltage JFET op-amps. If your existing board runs on ±15 V rails, this part drops straight in without a regulator change. The 5 mA supply current is modest for the bandwidth on offer. ## Temperature range — commercial only That is a commercial-grade part, so it belongs in bench instruments, office equipment, or indoor industrial control panels. Not rated for automotive under-hood or outdoor telecom cabinets where the ambient can dip below freezing. ## Package and footprint The surface-mount footprint is standard across the SOIC-8 family, so layout reuse with other single op-amps in the same package is straightforward. The shipping medium is Bulk — no tape-and-reel, so plan for tube or tray handling on the pick-and-place line. ## Lifecycle status No official successor has been declared.","metaTitle":"LF356BMX JFET Op-Amp, 5 MHz GBW, 12V/µs Slew Rate, 8-SOIC","metaDescription":"LF356BMX JFET input op-amp: 5 MHz GBW, 12V/µs slew rate, 30 pA bias current, 30-40 V supply.
