Additional Details:
The WM8532GEFL supports various audio data formats, including I2S, PCM, and TDM. It also features a programmable gain amplifier (PGA) for both the ADC and DAC, allowing for flexible signal conditioning. The integrated headphone amplifier is capable of driving a wide range of headphone impedances. This audio codec operates from a single 3.3V power supply, further simplifying system design and reducing power consumption. The device is typically available in a small QFN (Quad Flat No-leads) package, making it ideal for space-constrained applications. Further technical specs can be found on the datasheet provided by Cirrus Logic.
