ZHCSH28C September 2017 – May 2025 TPA3221
PRODUCTION DATA
AVDD and GVDD can be supplied either through the internal LDO or from external 5V power supply to power internal analog and digital circuits and the gate-drives for the output H-bridges. Proper connection, routing, and decoupling techniques are highlighted in the TPA3221 device EVM User's Guide (as well as the Section 9.1 section and Section 9.4.2 section) and must be followed as closely as possible for proper operation and performance. Deviation from the guidance offered in the TPA3221 device EVM User's Guide, which followed the same techniques as those shown in the Section 9.1 section, may result in reduced performance, errant functionality, or even damage to the TPA3221 device.
