12 Power Supply Recommendations

The TLV320AIC3262 integrates a large amount of digital and analog functionality, and each of these blocks can be powered separately to enable the system to select appropriate power supplies for desired performance and power consumption. The device has separate power domains for digital IO, digital core, analog core, analog input, receiver driver, charge-pump input, headphone driver, and speaker drivers. If desired, all of the supplies (except for the supplies for speaker drivers, which can directly connect to the battery) can be connected together and be supplied from one source in the range of 1.65 to 1.95 V. Individually, the IOVDD voltage can be supplied in the range of 1.1 V to 3.6 V. For improved power efficiency, the digital core power supply can range from 1.26 V to 1.95 V. The analog core voltages (AVDD1_18, AVDD2_18, AVDD4_18, and AVDD_18) can range from 1.5 V to 1.95 V. The microphone bias (AVDD3_33) and receiver driver supply (RECVDD_33) voltages can range from 1.65 V to 3.6 V. The charge-pump input voltage (CPVDD_18) can range from 1.26 V to 1.95 V, and the headphone driver supply (HVDD_18) voltage can range from 1.5 V to 1.95 V. The speaker driver voltages (SLVDD, SRVDD, and SPK_V) can range from 2.7 V to 5.5 V.

For more detailed information see the TLV320AIC3262 Applications Reference Guide, SLAU309.

12.1 Device Power Consumption

Device power consumption largely depends on PowerTune configuration. For information on device power consumption, see the TLV320AIC3262 Application Reference Guide, SLAU309.
