SLAS513C February 2007 – December 2014 TLV320AIC3105
The TLV320AIC3105 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.
IOVDD should be powered up 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.
|t1||IOVDD to AVDD, DRVDD||0||ms|
|t2||AVDD to DVDD||0||4|
|t3||IOVDD to DVDD||0|
