Replacement verdict
Not a drop-in replacement
The AD8022ARZ and AD80236BBCZRL are not functionally interchangeable; the AD80236BBCZRL is a higher-speed, lower-distortion amplifier in a different package and supply range, so the AD8022ARZ cannot be used as a direct substitute without circuit redesign and validation.

Key electrical and mechanical differences between the two devices
| Parameter | AD8022ARZ | AD80236BBCZRL | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 | 2 | Channel count must match the circuit's signal path requirements for direct substitution. |
| Supply Voltage Range | ±2.5 V to ±12 V (5 V to 24 V) | 2.7 V to 10 V | The available supply rails determine whether the part can operate in the target system without redesign. |
| -3 dB Bandwidth | 100 MHz | 55 MHz | Bandwidth limits the maximum signal frequency the amplifier can pass with acceptable gain. |
| Slew Rate | 100 V/µs | 35 V/µs | Slew rate affects large-signal transient response and distortion at high frequencies. |
| Input Voltage Noise Density | 2.5 nV/√Hz | 4.5 nV/√Hz | Lower input noise improves signal-to-noise ratio in low-level signal applications. |
| Input Offset Voltage | 1.5 mV (max) | 0.5 mV (max) | Offset voltage directly contributes DC error and affects precision in signal conditioning. |
| Quiescent Supply Current | 4 mA per amplifier | 2.6 mA per amplifier | Quiescent current impacts power budget and thermal performance in the design. |
| Package / Mounting | 8-Lead SOIC (surface mount) | 16-Lead LFCSP (surface mount) | Package footprint and pinout must be compatible with the PCB layout for drop-in replacement. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +125 °C | Temperature range must cover the application's environmental conditions for reliable operation. |

Frequently asked questions
Are the AD8022ARZ and AD80236BBCZRL interchangeable in an existing design?
No. The AD8022ARZ is a dual low-noise, high-speed voltage-feedback operational amplifier in an 8-lead SOIC package, while the AD80236BBCZRL is a quad high-speed operational amplifier in a 24-lead LFCSP package. The channel count, package, pinout, and supply/performance characteristics differ, so they are not drop-in replacements.
How do the channel counts of the AD8022ARZ and AD80236BBCZRL differ?
The AD8022ARZ integrates two operational amplifiers (dual), whereas the AD80236BBCZRL integrates four operational amplifiers (quad). Designs requiring two channels can use the AD8022ARZ, while the AD80236BBCZRL suits applications needing four channels in a single package.
What package types are used by the AD8022ARZ and AD80236BBCZRL?
The AD8022ARZ is supplied in an 8-lead SOIC package, and the AD80236BBCZRL is supplied in a 24-lead LFCSP package. The different footprints and pin counts mean PCB layouts are not compatible between the two parts.
Do the AD8022ARZ and AD80236BBCZRL have the same pinout?
No. Because the AD8022ARZ is an 8-lead dual amplifier and the AD80236BBCZRL is a 24-lead quad amplifier, their pin assignments and pin counts differ. Pin functions and supply/feedback connections must be verified against each device's respective datasheet before any layout work.
Are the supply voltage requirements of the AD8022ARZ and AD80236BBCZRL the same?
They should not be assumed identical. The AD8022ARZ is specified for operation on ±5 V to ±12 V dual supplies (10 V to 24 V total), while the AD80236BBCZRL operates from a single 5 V supply. The supply architecture and allowable voltage ranges differ, so power-rail design must be validated separately for each part.
Can the AD80236BBCZRL replace the AD8022ARZ in a low-noise signal-chain application?
Not directly. The AD8022ARZ is characterized as a low-noise, high-speed voltage-feedback amplifier with specified noise performance, whereas the AD80236BBCZRL is a quad high-speed amplifier with its own noise and bandwidth specifications. Noise, bandwidth, gain stability, and supply headroom must be compared from the respective datasheets before any substitution.
Which part should be selected when board space is the primary constraint?
Selection depends on channel count. For a two-channel function, the AD8022ARZ in an 8-lead SOIC is the smaller-footprint option. For a four-channel function, the AD80236BBCZRL in a 24-lead LFCSP consolidates four amplifiers into one package, which can reduce total board area compared with using multiple dual devices.
What should be verified before considering either the AD8022ARZ or AD80236BBCZRL for a new design?
Verify from the official manufacturer datasheets: channel count, package and pinout, supply voltage range, quiescent current, bandwidth, slew rate, noise density, input/output voltage ranges, and operating temperature range. Also confirm availability and lifecycle status through authorized distributors such as DigiKey, Mouser, or the manufacturer before finalizing the design.
