AD8429BRZ Equivalent & Substitute Parts

Part Overview

The AD8429BRZ is an instrumentation amplifier manufactured by Analog Devices Inc., designed for precision signal conditioning applications. This single-circuit, 8-SOIC surface mount device delivers high slew rate performance (22V/µs) and wide bandwidth (15 MHz) with low input offset voltage (50 µV) and minimal input bias current (150 nA). The device operates across a wide supply voltage range (8V to 36V) and maintains active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility cannot be achieved with the primary part due to inventory constraints, supply chain disruptions, or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AD8429BRZ are identified based on the following substitution criteria:

Primary Substitution Parameters:

• Package compatibility: 8-SOIC surface mount form factor
• Supply voltage range overlap: Minimum 8V to 36V operation capability
• Single-circuit configuration
• RoHS3 compliance and MSL rating
• Active product status
• Operating temperature range coverage

Substitution Logic:

The AD8429BRZ is an instrumentation amplifier with specific performance characteristics. Substitute parts are grouped into two categories based on functional equivalence:

1. Direct Instrumentation Amplifier Substitutes: Parts maintaining instrumentation amplifier topology with comparable slew rate, bandwidth, and input characteristics within the 8V to 36V supply range.

2. General Purpose Amplifier Substitutes: Parts with general purpose or voltage feedback amplifier topology that operate within overlapping supply voltage ranges and package specifications, suitable for applications where instrumentation-specific features are not critical.

All substitute parts maintain 8-SOIC package compatibility, surface mount mounting type, and RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

MAX410ESA+ Substitution: The MAX410ESA+ operates within a narrower supply voltage range (4.8V to 10.5V) compared to the AD8429BRZ (8V to 36V). This substitute is suitable for applications operating within the 8V to 10.5V window. The MAX410ESA+ exhibits lower slew rate (4.5V/µs versus 22V/µs) and reduced bandwidth (28 MHz gain-bandwidth product versus 15 MHz -3dB bandwidth). Both devices maintain RoHS3 compliance, MSL 1 rating, and active product status. The MAX410ESA+ is classified as a general purpose amplifier rather than instrumentation amplifier topology.

OP07CDR Substitution: The OP07CDR maintains the full supply voltage range (6V to 36V) with overlap at 8V to 36V operation. This substitute exhibits significantly reduced slew rate (0.3V/µs) and bandwidth (600 kHz) compared to the AD8429BRZ. The OP07CDR operates within a narrower temperature range (0°C to 70°C versus -40°C to 125°C). Both devices maintain RoHS3 compliance and MSL 1 rating. The OP07CDR is classified as a general purpose amplifier. This substitute is applicable only for low-frequency, low-speed applications.

OPA2354AIDGKR Substitution: The OPA2354AIDGKR operates within a narrower supply voltage range (2.5V to 5.5V) that does not overlap with the AD8429BRZ minimum requirement of 8V. This device contains two circuits versus one circuit in the AD8429BRZ. The OPA2354AIDGKR exhibits significantly higher slew rate (150V/µs) and bandwidth (250 MHz -3dB bandwidth). The package form factor differs (8-TSSOP/8-MSOP versus 8-SOIC). The OPA2354AIDGKR maintains RoHS3 compliance and active product status but carries MSL 2 rating (1 Year) versus MSL 1. This substitute is not recommended for direct replacement due to supply voltage incompatibility and package differences.

Frequently Asked Questions (FAQ)

Q: Can the MAX410ESA+ directly replace the AD8429BRZ in all applications?

A: The MAX410ESA+ is compatible only for applications operating within the 8V to 10.5V supply voltage range. Applications requiring operation above 10.5V or below 8V cannot use this substitute. Additionally, the MAX410ESA+ exhibits lower slew rate and bandwidth performance, making it unsuitable for high-speed signal conditioning applications.

Q: What are the key differences between the AD8429BRZ instrumentation amplifier and the OP07CDR general purpose amplifier?

A: The AD8429BRZ is designed specifically as an instrumentation amplifier with 22V/µs slew rate and 15 MHz bandwidth. The OP07CDR is a general purpose amplifier with 0.3V/µs slew rate and 600 kHz bandwidth. The OP07CDR is suitable only for low-frequency applications. Additionally, the OP07CDR operates within a narrower temperature range (0°C to 70°C versus -40°C to 125°C).

Q: Is the OPA2354AIDGKR a suitable substitute for the AD8429BRZ?

A: The OPA2354AIDGKR is not recommended as a direct substitute. The supply voltage range (2.5V to 5.5V) does not meet the AD8429BRZ minimum requirement of 8V. The package form factor differs (8-TSSOP/8-MSOP versus 8-SOIC). The OPA2354AIDGKR contains two circuits versus one circuit in the AD8429BRZ.

Q: What packaging considerations apply to these substitute parts?

A: The AD8429BRZ, MAX410ESA+, and OP07CDR all use 8-SOIC surface mount packages with 0.154" (3.90mm) width, ensuring mechanical compatibility on printed circuit boards. The OPA2354AIDGKR uses 8-TSSOP or 8-MSOP packaging (0.118", 3.00mm width), which differs from the primary part and requires board layout modifications.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed (MAX410ESA+, OP07CDR, OPA2354AIDGKR) maintain RoHS3 compliance status. The AD8429BRZ also carries RoHS3 compliance certification.

Q: What is the significance of Moisture Sensitivity Level (MSL) ratings?

A: The AD8429BRZ, MAX410ESA+, and OP07CDR carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions during storage and handling. The OPA2354AIDGKR carries MSL 2 (1 Year) rating, requiring controlled storage conditions and limiting shelf life to one year from the date of manufacture.

Q: Which substitute part maintains the widest operating temperature range?

A: Both the AD8429BRZ and OPA2354AIDGKR operate across -40°C to 125°C. The MAX410ESA+ operates across -40°C to 85°C. The OP07CDR operates across the narrowest range of 0°C to 70°C.
