Key Differentiators
- Integrated 1.3W stereo Class-D amplifier (vs TLV320AIC3101IRHBT)
- 32-bit audio resolution (vs TLV320AIC3101IRHBT)
- Pin-compatible with AIC3111 (vs TLV320AIC3111IRHBT)
Design Notes
Ensure proper decoupling of AVDD, DVDD, and IOVDD supplies. Place 0.1uF and 10uF capacitors close to each supply pin. The analog and digital supplies should be separated to minimize noise coupling. Use a low-noise LDO for AVDD to achieve optimal audio performance.
For the Class-D amplifier, place LC filters (e.g., 10uH inductor and 1uF capacitor) close to the SPKP and SPKM pins to reduce EMI and ensure stable operation. The exposed pad (EP) should be soldered to a large copper pour for thermal dissipation and connected to ground.
Avoid routing digital signals (I2C, MCLK) near analog audio traces to prevent crosstalk. Ensure the I2C address is correctly configured to avoid conflicts. The Class-D amplifier output should not be left floating; always connect a load or filter.
