- Higher DAC dynamic range (vs TLV320AIC3100)
Design Notes
The TAC5301-Q1 operates from a single 3.3V supply. Use a low-noise LDO to power AVDD and DVDD separately to minimize digital noise coupling into the analog domain. Place 100nF decoupling capacitors close to each power pin, and a 10uF bulk capacitor on the main supply. Ensure the power supply can handle the peak current during audio playback.
For optimal audio performance, separate analog and digital ground planes and connect them at a single point near the device. Route analog input/output traces away from digital signals to avoid interference. Use a solid ground plane under the VQFN package for thermal and electrical performance. Follow the layout guidelines in the datasheet for the exposed pad connection.
Avoid floating unused pins; connect them to ground or leave as NC per datasheet. Ensure the I2C address is correctly configured to avoid conflicts. The MCLK must be provided with low jitter; use a dedicated oscillator or clean clock source. Verify the audio interface format (TDM, I2S, LJ) matches the host processor to prevent data misalignment.
