HI Team,
I am using TAS5421-Q1 in my reference design for eCall. Please find my questions below:
- I see consumption of TAS5421-Q1 above 100mW.Schematic is attached( R50 and R51 are 51k, VOUT_U5 is 5V and VOUT_U6 is 9V). I think that TAS5421-Q1 consuming PVDD idle current typ 16mA. Am I correct?
- D/S information in Input voltage: Absolute Maximum Ratings is for SCL, SDA, STANDBY pin max 5V. in part of D/S: Recommended Operating Conditions:
- no limit for logic-level high STANDBY
- SCL pin input voltage for logic level high max 5.5V
- SDA pin input voltage for logic level high max 5.5V
Best regards
Lubomir
