Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AD4682BCPZ-RL is determined by strict equivalence across the following critical parameters:

Resolution and Sampling Performance: The substitute part must maintain 16-bit resolution and 1M SPS sampling rate to preserve signal fidelity and conversion speed in the application circuit.

Input Configuration: Both the main part and substitute must provide 2 pseudo-differential inputs with 2 independent SAR converters and simultaneous sampling capability.

Data Interface: Serial interface compatibility is required for proper communication with host processors and microcontrollers.

Supply Voltage Specifications: Analog supply voltage range (3V to 3.6V) and digital supply voltage range (1.65V to 3.6V) must be identical to ensure proper biasing and signal integrity.

Operating Temperature Range: The -40°C to 125°C operating range must be maintained for applications requiring extended temperature operation.

Package and Mechanical Compatibility: The 16-LFCSP (3x3) package designation and surface mount configuration must match exactly to ensure PCB layout compatibility and assembly process alignment.

Compliance and Certifications: ROHS3 compliance, REACH unaffected status, and MSL 3 moisture sensitivity rating must be equivalent across all substitute parts.

The AD4682BCPZ-RL7 meets all these criteria and is classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the AD4682BCPZ-RL and AD4682BCPZ-RL7 are active production components manufactured by Analog Devices Inc. with full ROHS3 compliance and REACH unaffected status. The parts are electrically and mechanically identical across all specified parameters, including resolution, sampling rate, input configuration, supply voltage ranges, operating temperature range, and package designation.

Selection between these parts is based on availability and supply chain considerations. The AD4682BCPZ-RL7 variant demonstrates higher current inventory levels (2490 pieces) compared to the AD4682BCPZ-RL (964 pieces), making it suitable for applications requiring immediate component procurement or high-volume production runs.

Both parts are suitable for direct substitution in existing circuit designs without modification to PCB layout, schematic connections, or firmware implementation. The identical 16-LFCSP (3x3) package ensures compatibility with existing assembly processes and thermal management strategies.

Frequently Asked Questions (FAQ)

Q: Can the AD4682BCPZ-RL7 be used as a direct replacement for the AD4682BCPZ-RL?
