Replacement verdict
Compatible functional replacement candidate
The AD8099ARD is a viable functional replacement candidate for the AD8092ARZ in high-speed signal-chain applications, provided the board layout is reviewed for the differing package footprint and the tighter supply-voltage headroom is validated. Both devices share a dual/single high-speed voltage-feedback architecture and similar bandwidth class, but the AD8099ARD offers substantially higher slew rate and lower distortion at the cost of reduced supply range and a different SOIC-8 pinout. Designers should confirm gain configuration, decoupling, and thermal layout before committing to the substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD8092ARZ | AD8099ARD | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 | 1 | Channel count determines how many independent signal paths can be processed; a dual op-amp cannot directly replace a single in multi-channel layouts without redesign. |
| Gain Bandwidth Product | 110 MHz | 700 MHz | GBW sets the maximum usable frequency for a given closed-loop gain; the much higher GBW of the AD8099 enables wider-bandwidth signal processing. |
| Slew Rate | 170 V/µs | 1350 V/µs | Slew rate limits how fast the output can respond to large signal steps; higher slew rate supports faster large-signal and pulse applications. |
| Input Voltage Noise Density | 16 nV/√Hz | 0.95 nV/√Hz | Lower input noise improves signal-to-noise ratio in low-level signal amplification; the AD8099 is far better suited to precision low-noise front ends. |
| Supply Voltage Range | 3 V to 12 V | 5 V to 12 V | The minimum supply voltage affects compatibility with low-voltage rails; the AD8092 can operate at 3 V while the AD8099 requires at least 5 V. |
| Input Offset Voltage (max) | 5 mV | 0.5 mV | Offset voltage causes DC error at the output; a lower offset reduces the need for trimming in precision DC-coupled designs. |
| Package / Mounting | 8-Lead SOIC (surface mount) | 8-Lead SOIC (surface mount) | Package and pinout determine board footprint and layout compatibility; both share SOIC-8 but differ in channel configuration and pin function. |
| Quiescent Supply Current per Amplifier | 4.8 mA | 15 mA | Quiescent current drives power budget and thermal load; the AD8099 consumes substantially more current for its higher performance. |
| Output Current (short-circuit) | 30 mA | 100 mA | Output drive capability affects ability to drive low-impedance loads or cables; higher output current supports heavier loads. |
