JFET op-amp for precision analog signal chains
Supply span runs from 9 V to 36 V total, so it works on ±5 V to ±18 V split rails or a single 12 V/24 V rail without an extra regulator.
At 20 V/µs the AD711JRZ can track a 10 V peak-to-peak sine wave up to roughly 318 kHz before slew-rate limiting sets in — adequate for audio processing, data acquisition front-ends, and control-loop compensation in switching power supplies. The 4 MHz -3 dB bandwidth supports moderate-speed filtering and anti-aliasing stages; for faster pulse work or video, a wider-bandwidth JFET op-amp like the AD823 (16 MHz) would be the next tier up. The 300 µV input offset is untrimmed; if sub-100 µV offset is needed, the AD711KRZ variant specifies 200 µV max.
Temperature grade and deployment envelope
It belongs in bench instruments, office equipment, consumer audio, and indoor telecom line cards — not in engine bays, outdoor enclosures, or factory-floor motor drives where the ambient can push past 70°C. For extended industrial or automotive environments, look at the AD711JRZ's industrial-temperature sibling (AD711BQ, -40°C to +85°C) if the rest of the BOM can tolerate a DIP or SOIC-8 package change.
Package, supply, and lifecycle
If your pick-and-place line prefers tape-and-reel, the AD711JRZ-REEL7 is the same die in a 7" reel carrier. Supply range spans 9 V to 36 V total, covering single-supply 12 V or 24 V systems and split ±5 V to ±18 V rails.
