Replacement verdict
Not a drop-in replacement
The AD8092ARZ and AD809BR are not functionally interchangeable. The AD8092ARZ is a dual, low-cost, high-speed voltage-feedback operational amplifier in an 8-lead SOIC package, while the AD809BR is a single high-speed voltage-feedback operational amplifier in an 8-lead SOIC package. The difference in channel count, supply voltage range, quiescent current, and bandwidth characteristics means the AD809BR cannot directly replace the AD8092ARZ in existing dual-amplifier circuit designs without significant redesign and validation.

Key electrical and mechanical differences between the two devices
| Parameter | AD8092ARZ | AD809BR | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 | 1 | Determines how many independent amplifier channels are available in a single package, directly affecting circuit architecture and channel count. |
| Package / Mounting Type | 8-SOIC (surface mount) | 8-SOIC (surface mount) | Both are 8-pin SOIC surface-mount devices, so board footprint and assembly process are compatible. |
| -3 dB Bandwidth | 160 MHz | 160 MHz | Sets the maximum usable signal frequency; matching bandwidth supports similar high-speed signal handling. |
| Slew Rate | 170 V/µs | 170 V/µs | Governs how fast the output can respond to large signal steps; identical slew rate preserves large-signal dynamic performance. |
| Supply Voltage Range | 3 V to 12 V | 3 V to 12 V | Defines the allowable power supply window; matching ranges allow the same supply rail design. |
| Input Offset Voltage (max) | 5 mV | 5 mV | Affects DC accuracy; equal offset limits mean comparable precision in DC-coupled applications. |
| Quiescent Supply Current per Amplifier | 4.5 mA | 4.5 mA | Impacts power budget and thermal design; identical current draw supports similar power planning. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Determines environmental robustness; matching ranges ensure equivalent operating conditions. |

Frequently asked questions
Are the AD8092ARZ and AD809BR functionally interchangeable?
No. The AD8092ARZ is a dual, low-cost, high-speed operational amplifier, while the AD809BR is a single high-speed operational amplifier. They differ in channel count, package, and pinout, so they are not direct substitutes.
How do the channel counts of the AD8092ARZ and AD809BR differ?
The AD8092ARZ integrates two operational amplifiers in one package, whereas the AD809BR contains a single operational amplifier. This affects board layout, power consumption budgeting, and channel density per package.
What package types are used for the AD8092ARZ and AD809BR?
The AD8092ARZ is supplied in an 8-lead SOIC (R-8) package. The AD809BR is supplied in an 8-lead PDIP (N-8) package. Package type and lead pitch differ, so PCB footprints are not compatible.
Do the AD8092ARZ and AD809BR have the same pinout?
No. Because one is a dual amplifier and the other is a single amplifier, the pin functions and assignments differ. The AD8092ARZ uses the standard dual op-amp pinout, while the AD809BR uses a single op-amp pinout with offset null capability. Direct pin-to-pin replacement is not possible.
How do the supply voltage ranges of the AD8092ARZ and AD809BR compare?
Both devices are specified for operation on dual supplies of ±5 V and single supplies from 5 V to 12 V, with absolute maximum supply of 13.2 V. The operating supply range is therefore comparable, but the AD809BR is a single amplifier and the AD8092ARZ is a dual amplifier.
What are the key AC specifications of the AD8092ARZ and AD809BR?
Both are high-speed voltage-feedback amplifiers with a −3 dB bandwidth of 110 MHz (G = +1) and a slew rate of 170 V/µs. These AC parameters are similar, but the channel count and package differences still prevent direct substitution.
Can the AD809BR be used as a replacement for one channel of the AD8092ARZ?
Only with a redesigned PCB. The AD809BR is a single amplifier in an 8-lead PDIP package, while the AD8092ARZ is a dual amplifier in an 8-lead SOIC package. Pinout, package footprint, and channel count differ, so a direct drop-in replacement is not possible without layout changes and validation against the manufacturer datasheets.
