Quad JFET op-amp in a 14-TSSOP — what the ratings mean for your signal chain
The AD8625ARUZ is a quad JFET-input operational amplifier from Analog Devices, packing four independent amplifiers into a 14-TSSOP surface-mount package. Each channel delivers a 5 MHz gain-bandwidth product and a 5 V/µs slew rate, with rail-to-rail output swing that lets you use the full supply range without headroom loss. The JFET front end keeps input bias current at 0.25 pA, making this part a natural fit for high-impedance sensor interfaces, photodiode amplifiers, and precision active filters where bias current drift would otherwise swamp the signal. Supply span runs from 5 V to 26 V single or dual supply, so it can sit on a ±15 V industrial rail or a 5 V single-supply data-acquisition bus without a separate regulator.
5 V/µs slew rate — not just a number
Slew rate is 5 V/µs. The 5 MHz GBW and 350 µV offset decide fit for precision loops.
Package and temperature grade
The 14-TSSOP footprint is 4.4 mm wide, which fits on dense mixed-signal boards where board area is at a premium. The -40°C to 85°C operating range covers industrial control cabinets, outdoor telecom enclosures, and benchtop instrumentation, but not under-hood automotive or downhole tools. The part ships in a Tube — if your pick-and-place line expects Tape & Reel, the AD8625ARZ-REEL7 variant uses the same die in a reel-compatible package.
Lifecycle and sourcing
The AD8625ARUZ is Active and ROHS3 compliant. It is a standard catalog part from Analog Devices, available through independent distribution. Sourced and quoted to order against an RFQ.
