ZHCSGI2E july 2017 – july 2023 TAS2505-Q1
PRODUCTION DATA
The TAS2505-Q1 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 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 supply can either be derived from the internal LDO accepting an SPKVDD voltage in the range of 2.7V to 5.5V or the AVDD pin can directly be driven with a voltage in the range of 1.5 V to 1.95 V. The speaker driver voltages (SPKVDD) can range from 2.7 V to 5.5 V.
