It combines a 3.5 MHz gain-bandwidth product with a 3V/µs slew rate, rail-to-rail output swing, and an input bias current of 0.25 pA. The device operates from a single 5 V supply up to 26 V dual supplies, and is rated over the -40°C to 125°C temperature range. This makes it a fit for precision signal conditioning in industrial sensor interfaces, data acquisition systems, and multichannel ADC driver stages where low input leakage and wide temperature tolerance are required. ## 0.25 pA input bias — what it means for your front-end The 0.25 pA typical input bias current is the standout parameter here. For a photodiode amplifier or a high-impedance sensor bridge, that leakage floor determines the minimum detectable signal. A CMOS-input op-amp might claim similar bias, but the JFET architecture also keeps voltage noise low at higher source impedances. The 70 µV input offset voltage is respectable for a general-purpose precision part — not the sub-10 µV class of auto-zero amplifiers, but well within what a 12-bit or 14-bit ADC driver needs after a gain stage. ## Rail-to-rail output and supply range The rail-to-rail output swings close to the supply rails. Supply range spans 5 V minimum to 26 V maximum. Each channel sources or sinks 12 mA. ## Active production — no last-time-buy scramble The AD8643ARZ-REEL7 carries an Active product status with ROHS3 compliance. ## Package and footprint for the layout The part comes in a 14-SOIC package with a 3.90 mm body width (0.154\"). Cut Tape quantities are also available for prototyping. Surface-mount only — no through-hole variant exists. The 14-SOIC footprint is standard, so existing land patterns for quad op-amps in this package work without modification.","metaTitle":"AD8643ARZ-REEL7 JFET Op-Amp, Quad, 3.5 MHz, 14-SOIC","metaDescription":"AD8643ARZ-REEL7 quad JFET op-amp from Analog Devices. 3.5 MHz GBW, 3V/µs slew rate, 0.25 pA bias, rail-to-rail output, -40 to 125°C.

The AD8625 offers a higher 5 MHz gain-bandwidth and 5 V/µs slew rate, but its input offset voltage is typically 350 µV versus 70 µV for the AD8643, and its temperature range is -40°C to 85°C rather than 125°C.
