WM8725CGED Equivalent & Substitute Parts

Part Overview

The WM8725CGED is a 24-bit audio DAC with 96 kHz sampling rate, designed for audio data acquisition applications. Manufactured by Cirrus Logic Inc., this component operates as a single-supply device with I2S digital interface. The product is currently obsolete, making identification of compatible substitute parts essential for system redesign, legacy product support, and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the WM8725CGED is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Package Type: 14-SOIC form factor (physical and electrical pin compatibility)
• Data Interface: I2S protocol support
• Number of Channels: 2-channel configuration
• Resolution: 24-bit minimum
• Operating Temperature Range: -40°C ~ 85°C coverage
• Mounting Type: Surface Mount

Allowable Parameter Variations:

• Sampling Rate: Substitute parts may exceed 96 kHz specification (higher sampling rates are backward compatible)
• Voltage Supply: Substitute parts may support wider voltage ranges or different supply configurations, provided the original 3V ~ 5V range is encompassed
• Product Status: Active products are preferred over obsolete components for new designs and long-term availability

The CS4354-CSZ meets all mandatory compatibility criteria while offering enhanced specifications in sampling rate (192 kHz) and supply voltage flexibility (1.4V ~ 5.25V).

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution: The CS4354-CSZ is the manufacturer-recommended substitute for the WM8725CGED. Both components share identical pin configurations in the 14-SOIC package, I2S interface protocol, 24-bit resolution, and 2-channel architecture. The operating temperature range is identical, ensuring thermal compatibility in existing designs.

Product Status Advantage: The CS4354-CSZ maintains active product status with current manufacturing and distribution support, whereas the WM8725CGED is obsolete. This transition is critical for long-term component availability and supply chain continuity.

Compliance and Certification: The CS4354-CSZ provides ROHS3 compliance, meeting current regulatory requirements for electronic components. Both parts maintain REACH Unaffected status and EAR99 export classification.

Performance Enhancement: The CS4354-CSZ supports 192 kHz sampling rate, exceeding the WM8725CGED specification of 96 kHz. This enhanced capability provides design flexibility for future audio processing requirements without functional degradation of existing 96 kHz implementations.

Supply Voltage Consideration: The CS4354-CSZ supports a wider supply voltage range (1.4V ~ 5.25V) compared to the WM8725CGED (3V ~ 5V). Designs operating within the original 3V ~ 5V window require no modification. The expanded lower voltage limit enables operation in low-power applications.

Frequently Asked Questions (FAQ)

Q: Can the CS4354-CSZ directly replace the WM8725CGED without PCB modifications?

A: Yes. Both components use identical 14-SOIC packaging with matching pin configurations. No PCB layout changes are required for physical substitution. Verify that your design operates within the overlapping supply voltage range (3V ~ 5V).

Q: What is the significance of the higher 192 kHz sampling rate on the CS4354-CSZ?

A: The CS4354-CSZ supports 192 kHz sampling, while the WM8725CGED is limited to 96 kHz. This enhanced specification is backward compatible—designs using 96 kHz operation will function identically on the substitute part. The higher capability provides design margin for future audio processing requirements.

Q: Are there any supply voltage compatibility issues?

A: The CS4354-CSZ supply range (1.4V ~ 5.25V) fully encompasses the WM8725CGED range (3V ~ 5V). Existing designs operating at 3V, 3.3V, or 5V require no modification. The expanded lower limit enables optional operation at reduced voltages if system design permits.

Q: What is the difference in Moisture Sensitivity Level between these parts?

A: The WM8725CGED is MSL 1 (unlimited moisture exposure tolerance), while the CS4354-CSZ is MSL 2 (1-year floor life limit). For standard manufacturing and assembly processes, this difference has minimal impact. Ensure proper storage conditions and handling procedures for the CS4354-CSZ to maintain component integrity.

Q: Is the CS4354-CSZ suitable for legacy product support?

A: Yes. The CS4354-CSZ is the manufacturer-recommended substitute and maintains active product status. It is appropriate for both new designs and legacy product updates where WM8725CGED components are no longer available.

Q: Are there any I2S protocol differences between these components?

A: Both components implement I2S digital audio interface protocol identically. No firmware or software modifications are required for I2S communication compatibility.
