Replacement verdict
Compatible functional replacement candidate
The AD8512ARZ and AD8510BR-REEL are both dual/quad precision JFET-input operational amplifiers from the same Analog Devices AD851x family, sharing core AC and DC performance characteristics. While the AD8512ARZ is a dual-channel device in an SOIC-8 package and the AD8510BR-REEL is a single-channel device in an SOIC-8 package, they are functionally interchangeable in applications where channel count and package footprint align. Designers should verify channel count requirements and confirm that the single-channel AD8510BR-REEL meets the circuit's needs before substituting for the dual AD8512ARZ.

Key electrical and mechanical differences between the two devices
| Parameter | AD8512ARZ | AD8510BR-REEL | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 (Dual) | 1 (Single) | Determines channel count; a dual cannot directly replace a single in a board layout without redesign. |
| Package / Mounting | 8-Lead SOIC | 8-Lead SOIC | Same footprint package allows physical drop-in compatibility on the PCB. |
| Input Offset Voltage (max) | 0.8 mV | 0.4 mV | Lower offset improves DC precision; the B-grade single offers tighter offset than the dual. |
| Input Bias Current (typ) | 25 pA | 25 pA | Very low JFET input bias current suits high-impedance sensor and precision applications. |
| Gain Bandwidth Product | 8 MHz | 8 MHz | Same GBW means comparable AC signal handling and closed-loop bandwidth. |
| Slew Rate | 20 V/µs | 20 V/µs | Identical slew rate supports similar large-signal transient response. |
| Supply Voltage Range | ±5 V to ±15 V | ±5 V to ±15 V | Matching supply range ensures compatibility with the same power rails. |
| Input Noise Voltage Density | 8 nV/√Hz | 8 nV/√Hz | Equal noise performance preserves signal-to-noise ratio in low-level signal chains. |
| Operating Temperature Range | -40°C to +125°C | -40°C to +125°C | Same industrial temperature range supports use in harsh environments. |
