AD8036ARZ Equivalent & Substitute Parts

Part Overview

The AD8036ARZ is an active linear voltage feedback amplifier manufactured by Analog Devices Inc. in 8-SOIC surface mount packaging. This single-circuit operational amplifier is designed for high-speed applications requiring wide bandwidth and fast slew rate performance. The device is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative topologies within specified electrical and mechanical constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8036ARZ with alternative operational amplifier devices is determined by alignment of critical electrical performance parameters and mechanical compatibility. The primary substitution candidate identified is the OPA2322SAIDGST from Texas Instruments.

Substitution logic is based on the following allowed parameters:

• Amplifier Architecture: Both voltage feedback and CMOS topologies are acceptable for general-purpose amplification applications where the specific feedback architecture does not impose design constraints
• Circuit Count: Single-circuit and multi-circuit configurations are interchangeable when only one channel is utilized in the application
• Slew Rate: The substitute device operates at lower slew rate (10 V/µs versus 1200 V/µs), limiting applicability to applications not requiring ultra-fast transient response
• Bandwidth: The substitute device provides significantly reduced bandwidth (20 MHz versus 240 MHz), restricting use to lower-frequency signal processing
• Supply Voltage Range: The substitute device operates within a narrower supply range (1.8 V to 5.5 V versus 6 V to 12 V), requiring verification of application supply voltages
• Output Current: Both devices provide comparable output current capability (65 mA to 70 mA per channel)
• Input Bias Current: The substitute device exhibits superior input bias current performance (0.2 pA versus 4 µA)
• Package Compatibility: The substitute device uses 10-VSSOP packaging, which differs from the 8-SOIC package of the main part, requiring PCB layout modification
• Compliance Status: Both devices maintain RoHS3 compliance and EAR99 classification

Parameter Comparison

Engineering Selection Recommendations

Selection between the AD8036ARZ and OPA2322SAIDGST is determined by application-specific electrical requirements and supply voltage constraints.

AD8036ARZ Selection Criteria:

• Applications requiring slew rate performance of 1200 V/µs or greater
• Signal processing circuits operating at bandwidth frequencies of 240 MHz or higher
• Systems with supply voltage requirements between 6 V and 12 V
• Designs requiring unlimited moisture sensitivity rating (MSL 1)
• Single-channel amplification configurations
• High-speed transient response applications

OPA2322SAIDGST Selection Criteria:

• Low-power applications with supply voltages between 1.8 V and 5.5 V
• Signal processing circuits operating at bandwidth frequencies of 20 MHz or lower
• Applications where input bias current minimization is critical (0.2 pA specification)
• Multi-channel configurations utilizing dual-circuit topology
• Extended operating temperature range requirements (-40°C to 125°C)
• Reduced power consumption priority (1.6 mA total supply current)

Both devices maintain Active product status, RoHS3 compliance, REACH unaffected status, and EAR99 export classification. Package differences (8-SOIC versus 10-VSSOP) require PCB layout redesign for physical substitution.

Frequently Asked Questions (FAQ)

Q: Can the OPA2322SAIDGST directly replace the AD8036ARZ in existing PCB designs?

A: Physical direct replacement is not possible due to package differences. The AD8036ARZ uses 8-SOIC packaging while the OPA2322SAIDGST uses 10-VSSOP packaging. PCB layout modification is required for footprint accommodation.

Q: What are the primary electrical differences between these devices?

A: The AD8036ARZ provides significantly higher slew rate (1200 V/µs versus 10 V/µs) and bandwidth (240 MHz versus 20 MHz gain-bandwidth product). The OPA2322SAIDGST offers superior input bias current performance (0.2 pA versus 4 µA) and operates at lower supply voltages (1.8 V to 5.5 V versus 6 V to 12 V).

Q: Is the OPA2322SAIDGST suitable for high-frequency applications?

A: The OPA2322SAIDGST is limited to applications with gain-bandwidth product of 20 MHz or lower. Applications requiring 240 MHz bandwidth performance require the AD8036ARZ or equivalent high-bandwidth devices.

Q: What supply voltage range must be verified before substitution?

A: The AD8036ARZ operates between 6 V and 12 V supply voltage. The OPA2322SAIDGST operates between 1.8 V and 5.5 V. Application supply voltage must fall within the selected device's specified range.

Q: Are both devices RoHS3 compliant?

A: Both the AD8036ARZ and OPA2322SAIDGST are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of the moisture sensitivity level difference?

A: The AD8036ARZ carries MSL 1 (unlimited moisture sensitivity), while the OPA2322SAIDGST carries MSL 2 (1 year moisture sensitivity). MSL 2 devices require controlled storage and handling conditions to prevent moisture absorption during storage periods exceeding one year.

Q: Can the dual-circuit OPA2322SAIDGST be used in single-channel applications?

A: The OPA2322SAIDGST contains two circuits. Single-channel applications utilize one circuit while the second circuit remains unused or is configured for alternative functions. This does not affect substitution validity for single-channel requirements.

Q: What is the operating temperature range difference?

A: The AD8036ARZ operates from -40°C to 85°C. The OPA2322SAIDGST operates from -40°C to 125°C, providing extended high-temperature performance capability.
