Replacement verdict
Compatible functional replacement candidate
The AD810TRZ-EP is a functionally compatible replacement candidate for the AD810ARZ, sharing the same high-speed video op-amp core, supply range, and SOIC-8 footprint, with the enhanced-product variant offering extended temperature screening. Designers should validate thermal margin and screening documentation before committing to the EP grade in production.

Key electrical and mechanical differences between the two devices
| Parameter | AD810ARZ | AD810TRZ-EP | Why it matters |
|---|---|---|---|
| Amplifier Type | Current Feedback | Current Feedback | Both are current-feedback op-amps, so the basic topology and feedback behavior are the same. |
| -3 dB Bandwidth | 80 MHz | 80 MHz | Bandwidth determines the maximum signal frequency the amplifier can handle with acceptable gain. |
| Slew Rate | 1000 V/µs | 1000 V/µs | Slew rate limits how fast the output can change, affecting large-signal and high-frequency performance. |
| Input Offset Voltage | 1.5 mV | 1.5 mV | Offset voltage introduces DC error at the output, important for precision signal chains. |
| Supply Voltage Range | ±5 V to ±15 V | ±5 V to ±15 V | The supply range must match the system rails for the part to operate correctly. |
| Supply Current | 6.8 mA | 6.8 mA | Quiescent current affects power budget and thermal design of the system. |
| Output Current | 50 mA | 50 mA | Output drive capability determines the load the amplifier can drive directly. |
| Operating Temperature Range | -40 °C to +85 °C | -55 °C to +125 °C | The extended temperature range of the EP version allows use in harsher environments and military/aerospace applications. |
| Package / Grade | 8-Lead SOIC (Commercial/Industrial) | 8-Lead SOIC (Enhanced Product) | The EP grade indicates enhanced screening and qualification, which affects reliability and sourcing for demanding applications. |

Frequently asked questions
What are the primary differences between the AD810ARZ and AD810TRZ-EP?
The AD810ARZ is the standard commercial-grade version of the AD810 video op amp in an 8-lead SOIC package, specified over the 0°C to +70°C temperature range. The AD810TRZ-EP is an enhanced-product (EP) variant of the same AD810 core, supplied in the same 8-lead SOIC package but manufactured and tested to support extended temperature operation and enhanced reliability screening per Analog Devices' enhanced product program. Both share the same functional amplifier topology and pinout.
Are the AD810ARZ and AD810TRZ-EP pin-compatible?
Yes. Both devices are offered in the 8-lead SOIC (R-8) package with the same pinout, so they are pin-compatible at the package level. Designers should still confirm the exact package suffix and land pattern against the respective datasheets before layout.
What is the specified operating temperature range for each part?
The AD810ARZ is specified for the commercial temperature range of 0°C to +70°C. The AD810TRZ-EP is an enhanced product intended for extended temperature environments; the exact specified range should be taken from the AD810TRZ-EP datasheet, as enhanced product grades are screened and specified differently from the standard commercial grade.
Do both parts share the same key AC and DC specifications?
Both are based on the AD810 video operational amplifier, which features 80 MHz unity-gain bandwidth (−3 dB), 1000 V/µs slew rate, and 0.1 dB gain flatness to 30 MHz, with low differential gain and phase error suitable for video applications. Because the TRZ-EP is a screened enhanced-product variant, the guaranteed limits and test conditions should be verified against the AD810TRZ-EP datasheet rather than assumed identical to the ARZ grade.
Can the AD810TRZ-EP be used as a drop-in replacement for the AD810ARZ?
Functionally and pin-wise, the AD810TRZ-EP can serve in the same socket as the AD810ARZ, since both are AD810 amplifiers in the 8-lead SOIC package. However, substitution should only be made after confirming that the TRZ-EP's specified temperature range, screening level, and any lot-specific limits meet the application's requirements, and after reviewing both datasheets.
What does the "EP" suffix indicate on the AD810TRZ-EP?
The "EP" designation denotes Analog Devices' Enhanced Product program, which applies additional manufacturing controls, extended temperature testing, and reliability screening beyond the standard commercial flow. This makes the TRZ-EP suited to applications requiring documented enhanced reliability, such as industrial or harsh-environment designs, whereas the ARZ is the standard commercial offering.
Which part should be selected for a standard commercial video design?
For a standard commercial video application operating within 0°C to +70°C, the AD810ARZ is the appropriate choice, as it is the commercial-grade device specified for that range. The AD810TRZ-EP should be reserved for designs that require the enhanced screening and extended temperature capability of the EP program.
