WM8725CGED/R Equivalent & Substitute Parts

Part Overview

The WM8725CGED/R is a 24-bit audio digital-to-analog converter (DAC) manufactured by Cirrus Logic Inc., designed for audio applications requiring 96 kHz sampling rate with I2S interface. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part operates across a single supply voltage range of 3V to 5V and is housed in a 14-SOIC surface mount package.

Key Parameters

Substitute Part Grouping Explanation

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

Package Compatibility: Both the main part and substitute must use the 14-SOIC surface mount package to ensure direct PCB compatibility without layout modifications.

Interface Compatibility: The I2S digital audio interface is mandatory for signal compatibility with existing host controllers and audio processing chains.

Resolution and Channel Configuration: The 24-bit resolution and 2-channel stereo configuration must be maintained to preserve audio quality and system architecture.

Operating Temperature Range: The substitute must support the full -40°C to 85°C operating range to ensure reliability across specified environmental conditions.

Voltage Supply Architecture: While the main part operates on single supply (3V to 5V), substitute parts may employ different supply architectures provided they support the required voltage levels for system integration.

The CS4354-CSZR qualifies as a direct substitute based on these parameters: identical package (14-SOIC), matching I2S interface, equivalent 24-bit resolution with 2-channel configuration, compatible operating temperature range, and overlapping supply voltage support (1.4V to 5.25V encompasses the 3V to 5V requirement).

Engineering Selection Recommendations

The CS4354-CSZR is the qualified substitute for the WM8725CGED/R based on the following engineering criteria:

Product Status: The WM8725CGED/R is obsolete, while the CS4354-CSZR maintains active production status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: The CS4354-CSZR is ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components in most jurisdictions.

Functional Equivalence: Both parts share identical package geometry, I2S interface protocol, 24-bit resolution, 2-channel configuration, and compatible operating temperature ranges. The CS4354-CSZR supports higher sampling rates (192 kHz versus 96 kHz), providing enhanced performance capability without compromising backward compatibility.

Supply Voltage Compatibility: The CS4354-CSZR supply voltage range (1.4V to 5.25V) encompasses the WM8725CGED/R requirement (3V to 5V), ensuring direct integration into existing power distribution architectures.

Inventory Availability: The CS4354-CSZR has significantly higher inventory availability (35,200 units) compared to the obsolete WM8725CGED/R, supporting both immediate procurement and long-term production needs.

Frequently Asked Questions (FAQ)

Q: Can the CS4354-CSZR be used as a direct replacement without PCB modifications?

A: Yes. Both parts use identical 14-SOIC package geometry with matching pin assignments for the I2S interface and power connections. No PCB layout changes are required for physical substitution.

Q: What is the significance of the higher 192 kHz sampling rate in the CS4354-CSZR?

A: The CS4354-CSZR supports 192 kHz sampling, compared to the WM8725CGED/R's 96 kHz capability. This enhanced specification is backward compatible; systems designed for 96 kHz operation will function correctly with the substitute part at the original sampling rate.

Q: Are there differences in power supply requirements between these parts?

A: The WM8725CGED/R operates on a single 3V to 5V supply. The CS4354-CSZR uses separate analog and digital supply pins with a combine
