JFET input, military temperature range — what this op-amp brings to the bench
Its 4 pA input bias current and 600 µV input offset voltage suit precision analog front-ends where FET-input isolation matters — photodiode transimpedance amplifiers, high-impedance sensor buffers, and sample-and-hold stages. The 2 MHz gain-bandwidth product and 3.4 V/µs slew rate cover audio-band filtering, control-loop compensation, and low-speed data acquisition without excess phase lag. Supply range spans 7 V to 36 V, so a single 12 V or 24 V industrial rail works, as do split ±15 V supplies.
The military temperature range (-55°C to 125°C) is the main differentiator from commercial-grade JFET op-amps — it qualifies the part for avionics, satellite, missile guidance, and downhole instrumentation where the ambient exceeds standard industrial limits.
Slew rate and GBW — what they mean for signal fidelity
The 3.4 V/µs slew rate means the output can swing 3.4 V in one microsecond. For a 2 V peak-to-peak sine wave, that supports frequencies up to roughly 270 kHz before slew-rate limiting distorts the waveform — adequate for audio, ultrasonic drivers, and many control loops. The 2 MHz gain-bandwidth product sets the closed-loop bandwidth: at a gain of 10, the -3 dB point lands near 200 kHz. Together these ratings tell the designer that this op-amp is not a high-speed video or RF part; it is sized for precision analog signal conditioning where bandwidth is modest but input bias current and temperature range are the critical specs.
Supply voltage flexibility and output drive
The 7 V to 36 V supply span covers most industrial and military rail voltages without an extra regulator. Running from ±15 V gives the full output swing headroom; running from a single 12 V rail still leaves margin above the 7 V minimum. The 80 mA output current per channel is high for a JFET op-amp — it can drive a 32 Ω headphone, a small solenoid, or the analog input of a successive-approximation ADC without an external buffer. Quiescent supply current is 290 µA, so the part does not waste power when the output is idle.
