TLV320AIC3104-Q1: Current Values at 75 and 85 degree Celsius

Josef Warta

Hello Team,

do we have current values of I_{AVDD_ADC}, I_{AVDD_DAC}, I_{AVDD_LINE}, I_{AVDD_PLL}, I_{DVDD_ADC}, I_{DVDD_DAC}, I_{DVDD_LINE}, I_{DVDD_} at 75 and 85 C ?

Customer needs this for their simulation.

Many Thanks

Josef

Joseph,

Thank you for your query. Please help us with the below questions:

Supply voltages in use
Data rates for record/playback path
Are both the channels used?
Any other set up information would be useful.

Thanks,

Krunal

Hi Krunal,

Thanks for your help.

With the following set-up :

AVDD Supply: 3,3 V

DVDD Supply: 1,8 V

3G eCall with 1kHz sinus via eCall amplifier 4 Ohm @ 24dBm
Audio input: 1kHz sinus signal @ Class-D
Speaker output power (1kHz @ 4 Ohm): 10W
The both channels used

Thank you

Ahmed

Hello Ahmed,

Our design engineer informed that typically the currents for (IDRVDD + IAVDD) and (IDVDD) at AVDD = DRVDD = 3.3 V, and DVDD = 1.8 V, at 75C/85C should be within 4% of these current consumptions at 25C. Please let me know if you have any questions.

Thanks,
Krunal
