11 Power Supply Recommendations

The TLV320AIC3104-Q1 has been designed to be extremely tolerant of power supply sequencing. However, in some rare instances, unexpected conditions can be attributed to power supply sequencing. The following sequence will provide the most robust operation.

Power up IOVDD first. The analog supplies, which include AVDD and DRVDD, should be powered up second. The digital supply DVDD should be powered up last. Keep RESET low until all supplies are stable. The analog supplies should be greater than or equal to DVDD at all times.
