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

Key electrical and mechanical differences between the two devices
| Parameter | AD810ARZ | AD810TRZ-EP-RL | Why it matters |
|---|---|---|---|
| Amplifier Type | Current Feedback | Current Feedback | Both are current-feedback op-amps, so the fundamental topology and feedback behavior are the same, supporting substitutability. |
| Number of Channels | 1 | 1 | Single-channel configuration must match for pin-compatible replacement in a given circuit. |
| -3 dB Bandwidth | 80 MHz | 80 MHz | Bandwidth determines the maximum signal frequency the amplifier can handle; identical values mean equivalent high-frequency performance. |
| Slew Rate | 1000 V/µs | 1000 V/µs | Slew rate limits large-signal transient response; matching values ensure comparable pulse and step behavior. |
| Supply Voltage Range | ±5 V to ±15 V (dual) | ±5 V to ±15 V (dual) | Compatible supply ranges allow the parts to operate in the same power rails without redesign. |
| Input Offset Voltage | 1.5 mV (typ) | 1.5 mV (typ) | Offset voltage affects DC accuracy; identical typical values indicate similar precision in DC-coupled applications. |
| Package / Mounting | 8-Lead SOIC (surface mount) | 8-Lead SOIC (surface mount) | Same package and mounting style enable direct board-level replacement without layout changes. |
| Operating Temperature Range | -40 °C to +85 °C | -55 °C to +125 °C | The enhanced-product variant supports a wider military/industrial temperature range, which matters for harsh-environment applications. |
| Product Grade / Screening | Standard commercial grade | Enhanced Product (EP) grade | EP parts undergo additional screening and qualification, affecting reliability assurance and cost for critical applications. |

Frequently asked questions
What are the key differences between the AD810ARZ and AD810TRZ-EP-RL?
The AD810ARZ is the standard commercial-grade version in an 8-lead SOIC package, specified over the 0°C to +70°C temperature range. The AD810TRZ-EP-RL is an enhanced-product (EP) variant supplied in tape-and-reel packaging and is specified over the extended industrial temperature range of −40°C to +85°C. Both are based on the same AD810 high-speed, low-power video operational amplifier core.
Are the AD810ARZ and AD810TRZ-EP-RL functionally interchangeable?
Both devices share the same AD810 amplifier core and the same 8-lead SOIC (R-8) package pinout, so they are functionally equivalent in circuit topology. However, the AD810TRZ-EP-RL is qualified for the extended −40°C to +85°C range, while the AD810ARZ is specified only over 0°C to +70°C. Substitution is acceptable only when the application's operating temperature range and packaging requirements are validated against the respective datasheets.
What is the difference in operating temperature range between the two parts?
The AD810ARZ is specified for operation from 0°C to +70°C. The AD810TRZ-EP-RL is specified for operation from −40°C to +85°C. Designs that must operate below 0°C or above +70°C should use the AD810TRZ-EP-RL rather than the AD810ARZ.
What package and pinout do the AD810ARZ and AD810TRZ-EP-RL use?
Both devices are offered in the 8-lead SOIC package (R-8 suffix) with the same pin configuration, allowing them to share a common PCB footprint. The AD810TRZ-EP-RL is additionally supplied in tape-and-reel format (RL suffix) for automated assembly, whereas the AD810ARZ is supplied in standard tube packaging.
What are the key AC and DC specifications of the AD810 amplifier?
The AD810 is a high-speed, low-power operational amplifier with a −3 dB bandwidth of 80 MHz (G = +1), a slew rate of 1000 V/µs, and a 0.1% settling time of 45 ns. It operates on ±5 V to ±15 V dual supplies and typically draws 6.8 mA of supply current. These core specifications apply to both the AD810ARZ and AD810TRZ-EP-RL.
Does the AD810TRZ-EP-RL support automotive or military qualification?
The "EP" designation indicates an enhanced-product variant with an extended industrial temperature range of −40°C to +85°C. It should not be assumed to carry automotive (AEC-Q100) or military (QML) qualification unless explicitly stated in the manufacturer's datasheet or ordering guide. Designers requiring such qualifications must verify them against official Analog Devices documentation.
Which part should be selected for a design operating below 0°C?
The AD810TRZ-EP-RL should be selected, because its specified operating temperature range extends down to −40°C. The AD810ARZ is specified only from 0°C to +70°C and is not guaranteed to meet datasheet limits below 0°C.
Are the AD810ARZ and AD810TRZ-EP-RL RoHS compliant?
Both part numbers carry the "Z" suffix, which in Analog Devices nomenclature denotes RoHS-compliant, lead-free (Pb-free) packaging. Designers should confirm the current compliance status on the official Analog Devices product page or an authorized distributor listing before finalizing a bill of materials.
