Replacement verdict
Compatible functional replacement candidate
The AD8062ARZ and AD8063AR-REEL7 are both dual, high-speed voltage-feedback operational amplifiers from Analog Devices sharing the same SOIC-8 package and similar gain-bandwidth characteristics, making the AD8063AR-REEL7 a viable functional substitute for the AD8062ARZ in many designs. However, the AD8063 offers a dedicated disable feature and lower quiescent current, while supply voltage range, output drive, and packaging format differ enough that engineers should validate the specific operating conditions before committing to a drop-in swap.

Key electrical and mechanical differences between the two devices
| Parameter | AD8062ARZ | AD8063AR-REEL7 | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 (Dual) | 1 (Single) | Channel count determines whether one package can serve two signal paths; a dual cannot be dropped into a single-amplifier socket without layout changes. |
| Package / Case | 8-SOIC (SOIC-8) | 8-SOIC (SOIC-8) | Both use the same 8-lead SOIC footprint, but pin assignments differ between single and dual devices, so board routing must be verified. |
| -3 dB Bandwidth | 320 MHz (G = +1) | 320 MHz (G = +1) | Bandwidth sets the maximum signal frequency the amplifier can pass with acceptable gain flatness; matching values support similar high-speed signal chains. |
| Slew Rate | 650 V/µs | 650 V/µs | Slew rate limits large-signal transient response; identical slew rates mean comparable distortion behavior on fast edges. |
| Supply Voltage Range | 2.7 V to 8 V (single supply) | 2.7 V to 8 V (single supply) | The usable supply window must match the system rail; identical ranges allow the same power design to be reused. |
| Input Offset Voltage (max) | 1 mV | 1 mV | Offset voltage directly adds DC error at the output; equal limits mean comparable precision in DC-coupled applications. |
| Quiescent Supply Current per Amplifier | 6.8 mA (typ, per amp) | 6.8 mA (typ) | Quiescent current drives power budget; matching per-amplifier current keeps thermal and supply loading predictable. |
| Output Current (short-circuit) | 50 mA (typ) | 50 mA (typ) | Output drive capability determines the load the amplifier can drive; equal values support similar cable and ADC driving duties. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | The temperature range must cover the application environment; identical ratings allow the same thermal qualification. |

Frequently asked questions
What are the primary differences between the AD8062ARZ and AD8063AR-REEL7?
The AD8062ARZ is a dual, low-cost, high-speed voltage feedback amplifier supplied in an 8-lead SOIC package (RoHS-compliant, tube/tray packaging). The AD8063AR-REEL7 is a single, high-speed voltage feedback amplifier with a disable feature, supplied in a 6-lead SOT-23 package on a 7-inch reel. The AD8062 offers two amplifiers per package, while the AD8063 offers one amplifier plus a power-down pin.
Are the AD8062ARZ and AD8063AR-REEL7 pin-compatible?
No. The AD8062ARZ uses an 8-lead SOIC pinout (two amplifiers), while the AD8063AR-REEL7 uses a 6-lead SOT-23 pinout (single amplifier with disable). The package types, pin counts, and pin functions differ, so they are not drop-in replacements for each other.
What are the key AC specifications of these amplifiers?
Both devices are high-speed voltage feedback amplifiers with a −3 dB bandwidth of approximately 300 MHz (G = +1) and a slew rate of approximately 650 V/µs, per the Analog Devices datasheets. These specifications make them suitable for video, ADC driving, and other high-speed signal-chain applications.
Does the AD8063AR-REEL7 include a power-down feature?
Yes. The AD8063 is a single amplifier that includes an active-low disable pin, allowing the output to be placed in a high-impedance state to reduce power consumption. The AD8062ARZ, being a dual amplifier without a disable pin, does not offer this power-down capability.
What supply voltage range do the AD8062ARZ and AD8063AR-REEL7 support?
Both devices operate from a single supply of 2.7 V to 12 V or a dual supply of ±1.35 V to ±6 V, as specified in the Analog Devices datasheets. This wide supply range supports both portable and industrial signal-processing designs.
Which part should be selected for a dual-channel design versus a single-channel design?
For a dual-channel signal path requiring two amplifiers in one package, the AD8062ARZ is the appropriate choice. For a single-channel design that also requires power-down capability, the AD8063AR-REEL7 is appropriate. Selection should be based on channel count, package footprint, and the need for a disable function.
Are both parts RoHS-compliant and available in production packaging?
The AD8062ARZ is supplied in a RoHS-compliant 8-lead SOIC package. The AD8063AR-REEL7 is supplied in a 6-lead SOT-23 package on a 7-inch reel for automated assembly. Designers should confirm the current RoHS status and packaging options against the latest Analog Devices datasheet and distributor listing before production release.
