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. |

Frequently asked questions
What are the primary differences between the AD8512ARZ and AD8510BR-REEL?
The AD8512ARZ is a dual, low-noise, low-input-bias-current operational amplifier in an 8-lead SOIC package, while the AD8510BR-REEL is a single, low-noise, low-input-bias-current operational amplifier in an 8-lead SOIC package supplied on tape and reel. The AD8512ARZ integrates two amplifiers per package, whereas the AD8510BR-REEL contains one amplifier per package.
Are the AD8512ARZ and AD8510BR-REEL pin-compatible?
No. The AD8512ARZ is a dual op amp with both amplifiers' inputs and outputs assigned across the 8-lead SOIC pins, while the AD8510BR-REEL is a single op amp with a different pin function assignment on the same 8-lead SOIC footprint. They are not direct drop-in replacements for each other.
Do both parts share the same input bias current and noise characteristics?
Both the AD8512 and AD8510 are members of the same low-noise, low-input-bias-current op amp family, and their datasheets specify comparable input bias current and voltage noise performance. However, exact guaranteed limits should be verified on each product's respective datasheet, as the AD8512ARZ and AD8510BR-REEL are separate orderable part numbers with their own specification tables.
What supply voltage range do the AD8512ARZ and AD8510BR-REEL support?
Both devices are specified for dual-supply operation of ±5 V to ±15 V (or single-supply equivalents within that total range), consistent with the AD8512 and AD8510 datasheet specifications. Designers should confirm the exact supply range and absolute maximum ratings on the official manufacturer datasheet for each part number.
Why would a design choose the AD8512ARZ over the AD8510BR-REEL?
The AD8512ARZ provides two amplifiers in a single 8-lead SOIC package, which reduces board space and component count in dual-channel signal chains. The AD8510BR-REEL provides a single amplifier and is supplied in tape-and-reel packaging, which suits automated high-volume assembly for single-channel designs.
Are the AD8512ARZ and AD8510BR-REEL available in the same package type?
Both are offered in an 8-lead SOIC package (the "R" suffix in the AD8512ARZ and the AD8510BR-REEL denotes the SOIC package). The AD8510BR-REEL is additionally supplied in tape-and-reel format for automated placement, while the AD8512ARZ is typically supplied in tube or standard packaging depending on the distributor.
Can the AD8510BR-REEL be used to replace one channel of an AD8512ARZ design?
Functionally, a single AD8510 amplifier can serve one channel of a dual AD8512 design, but it is not a pin-for-pin replacement because the pinouts differ. Any substitution requires a PCB layout change and validation against the manufacturer datasheets for both parts.
What are the typical applications for these op amps?
Both the AD8512 and AD8510 are low-noise, low-input-bias-current op amps suited to precision signal conditioning, active filtering, photodiode and sensor interfacing, and audio or instrumentation front ends. The dual AD8512ARZ suits multi-channel signal paths, while the single AD8510BR-REEL suits single-channel high-volume assemblies.
