AD7899ARSZ-3 Equivalent & Substitute Parts

Part Overview

The AD7899ARSZ-3 is a 14-bit Analog to Digital Converter (ADC) manufactured by Analog Devices Inc., designed for single-ended input data acquisition applications. This SAR (Successive Approximation Register) architecture device operates at 400k samples per second with parallel data interface output. The part is currently in active production status and is ROHS3 compliant, making it suitable for modern electronic applications requiring precision analog signal conversion.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility allows for functionally identical alternatives from the same manufacturer.

Key Parameters

Substitute Part Grouping Explanation

The AD7899ARSZ-3 has one parametric equivalent substitute: AD7899ARSZ-1. Both parts share identical electrical and mechanical specifications across all critical parameters that determine functional interchangeability. The substitution is valid based on the following key parameters:

• 14-bit resolution
• 400k samples per second sampling rate
• Single-ended input configuration
• Parallel data interface
• SAR architecture
• 5V analog and digital supply voltages
• -40°C to 85°C operating temperature range
• 28-SSOP surface mount package
• ROHS3 compliance
• MSL 3 rating

The difference between these part numbers relates to internal reference voltage specifications (indicated by the suffix -3 versus -1), which do not affect the core functional parameters or physical compatibility in applications where the reference configuration is appropriate for the design.

Parameter Comparison

Engineering Selection Recommendations

Both the AD7899ARSZ-3 and AD7899ARSZ-1 are active production parts from Analog Devices Inc. with identical ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on reference voltage requirements specific to your application design. Both parts maintain full compliance with current environmental and regulatory standards, ensuring long-term availability and supply chain stability.

The AD7899ARSZ-1 currently has higher inventory availability (1533 pcs) compared to the AD7899ARSZ-3 (847 pcs), which may influence sourcing decisions when lead times or bulk procurement are considerations.

Frequently Asked Questions (FAQ)

Q: Can AD7899ARSZ-1 be used as a direct replacement for AD7899ARSZ-3?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. The suffix difference (-3 versus -1) indicates internal reference voltage configuration. Substitution is valid when the reference voltage specification of your design accommodates the alternative part number.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the identical 28-SSOP surface mount package with 0.209" width (5.30mm). Pinout and PCB footprint compatibility is guaranteed.

Q: Do both parts meet the same compliance standards?

A: Yes. Both AD7899ARSZ-3 and AD7899ARSZ-1 are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: What is the significance of the part number suffix (-3 versus -1)?

A: The suffix indicates the internal reference voltage specification. This affects the reference configuration but does not change the core functional parameters, resolution, sampling rate, or package specifications.

Q: Can these parts be used interchangeably in production?

A: Yes, provided your circuit design and reference voltage requirements are compatible with the alternative part number. Both parts maintain identical performance characteristics across all specified parameters.
