JFET input stage — why the 3 pA bias matters
The AD8610ARZ-REEL7 is a single-channel JFET-input operational amplifier from Analog Devices. Its 3 pA typical input bias current means negligible DC error when buffering high-impedance sources like photodiodes, pH probes, or piezoelectric sensors. The 25 MHz gain-bandwidth product and 60 V/µs slew rate together support fast settling for ADC drivers and active filters up to several MHz. Supply span runs from 10 V to 26 V, so you can run it on ±5 V to ±13 V split rails or a single 12 V or 24 V industrial rail.
Package and layout — standard SOIC-8, no surprises
The 8-SOIC package with 0.154-inch body width and 3.90 mm footprint is one of the most common op-amp packages. Surface-mount only. No exposed pad to route, no thermal-via array needed — just the usual 0.1 µF decoupling cap within 5 mm of each supply pin. The single-channel layout leaves the other seven pins for feedback and input networks, which keeps the routing clean for high-impedance or high-frequency paths.
