Replacement verdict
Compatible functional replacement candidate
The AD8062ARZ and AD8063AR are both dual, high-speed voltage-feedback operational amplifiers from Analog Devices in the same 8-lead SOIC package, sharing core AC and DC performance characteristics. The AD8063AR adds a disable feature that the AD8062ARZ does not provide, so the AD8063AR can serve as a functional substitute for the AD8062ARZ when the shutdown pin is properly handled, while the reverse substitution requires validation of the disable-pin behavior.

Key electrical and mechanical differences between the two devices
| Parameter | AD8062ARZ | AD8063AR | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 (Dual) | 1 (Single) | Channel count determines whether the part can replace a dual-amplifier circuit or only a single-amplifier circuit; they are not directly interchangeable. |
| Package / Mounting Type | 8-Lead SOIC (surface mount) | 8-Lead SOIC (surface mount) | Both use the same 8-lead SOIC footprint, but pinout differs due to single vs dual configuration, affecting board layout compatibility. |
| -3 dB Bandwidth | 320 MHz (G = +1) | 320 MHz (G = +1) | Bandwidth indicates the maximum signal frequency the amplifier can handle with acceptable gain; matching values suggest similar high-speed capability. |
| Slew Rate | 650 V/µs | 650 V/µs | Slew rate limits how fast the output can respond to large signal swings; identical values indicate comparable large-signal dynamic performance. |
| Supply Voltage Range | 2.7 V to 8 V (single supply) | 2.7 V to 8 V (single supply) | The supply range defines the operating voltage window; matching ranges allow use in the same power rail designs. |
| Input Offset Voltage (max) | 1.5 mV | 1.5 mV | Offset voltage affects DC accuracy; identical maximum offset means similar precision in DC-coupled applications. |
| Quiescent Supply Current per Amplifier | 6.8 mA (per amplifier) | 6.8 mA | Quiescent current impacts power budget; comparable per-amplifier current means similar power consumption for equivalent channel count. |
| Output Current (short-circuit) | 50 mA | 50 mA | Output drive capability determines load-driving ability; matching values indicate similar drive strength for resistive/capacitive loads. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Temperature range defines environmental limits; identical ranges allow use in the same operating environments. |

Frequently asked questions
What are the primary differences between the AD8062ARZ and the AD8063AR?
The AD8062ARZ is a dual, low-cost, high-speed voltage feedback amplifier supplied in an 8-lead SOIC package, while the AD8063AR is a single, high-speed voltage feedback amplifier with a disable feature supplied in an 8-lead SOIC package. The AD8062ARZ integrates two amplifiers per package, whereas the AD8063AR contains one amplifier plus a power-down (disable) pin.
Are the AD8062ARZ and AD8063AR pin-compatible?
No. The AD8062ARZ is a dual amplifier in an 8-lead SOIC with both amplifiers' inputs and outputs assigned to the eight pins, while the AD8063AR is a single amplifier in an 8-lead SOIC that uses one pin for the DISABLE function. The pin functions and assignments differ, so they are not drop-in replacements for each other.
What are the key AC specifications of the AD8062ARZ?
Per the Analog Devices datasheet, the AD8062ARZ offers a -3 dB bandwidth of 300 MHz (G = +1), a slew rate of 650 V/µs, and a settling time of 16 ns to 0.1%. These specifications suit it for high-speed signal conditioning and video applications.
What are the key AC specifications of the AD8063AR?
Per the Analog Devices datasheet, the AD8063AR offers a -3 dB bandwidth of 300 MHz (G = +1), a slew rate of 650 V/µs, and a settling time of 16 ns to 0.1%, matching the core amplifier performance of the AD8062ARZ but in a single-amplifier configuration with disable capability.
What supply voltage range do the AD8062ARZ and AD8063AR 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 datasheet. This wide range supports portable, battery-powered, and industrial systems.
Does the AD8063AR include a power-down feature, and does the AD8062ARZ?
Yes, the AD8063AR includes an active-low DISABLE pin that places the amplifier in a low-power shutdown state, reducing quiescent current. The AD8062ARZ does not provide a disable pin; both of its amplifiers remain active whenever power is applied.
What are the input bias current and offset voltage specifications for these amplifiers?
Per the Analog Devices datasheet, both the AD8062ARZ and AD8063AR feature a low input bias current of 6 pA typical and an input offset voltage of 1 mV typical (5 mV maximum). These low values make them suitable for high-impedance sensor interfaces and precision signal chains.
In what applications would the AD8062ARZ be preferred over the AD8063AR?
The AD8062ARZ is preferred when two matched high-speed amplifiers are needed in a single package, such as differential signal chains, dual-channel video buffering, or I/Q processing, saving board space and cost. The AD8063AR is preferred when a single amplifier with power-down capability is required for power-sensitive or multiplexed signal paths.
