Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WM8912CGEFL/V is determined by the following critical parameters:

• Resolution and Sampling Rate: 24-bit resolution at 96 kHz sampling rate
• Channel Configuration: 2-channel audio DAC
• Data Interface: DSP and I2S protocol support
• Supply Voltage Range: 0.95V ~ 1.98V and 1.71V ~ 2V
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 32-WFQFN Exposed Pad (32-QFN 4x4)
• Mounting: Surface Mount

The WM8918CGEFL/V meets all these core electrical and mechanical parameters, establishing it as a direct functional equivalent. Both components share identical resolution, sampling rate, channel count, interface protocols, voltage specifications, temperature range, and physical packaging.
