JAJSDO3A August 2017 – November 2017 TLV320AIC3109-Q1
PRODUCTION DATA.
The TLV320AIC3109-Q1 is 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 provides the most robust operation.
Power-up IOVDD first. Power-up the analog supplies, which includes AVDD and DRVDD, second. Power-up the digital supply DVDD last. Keep RESET low until all supplies are stable. The analog supplies must be greater than or equal to DVDD at all times. Figure 191 and Table 167 detail the preferred power-supply sequence.
