TAS2505: I2C Address Selection, Startup Time, and Quiescent Current
1. On the datasheet, it seems like the I2C address for TAS2505 is fixed. I was wondering if there is a way to change the I2C address for the individual TAS2505 modules so that we can send I2C messages to two TAS2505's connected by the same SCL and SDA line at the same time? And could you please tell us how to change the I2C address as well?
3. What are the exact values for TAS2505's start-up time and the quiescent current (Iq)?
If you're looking for the time it takes from the Class-D power up command through I2C to the signal becomes present at the output of the amplifier, this is in the order of tenths of milliseconds. This depends on settings like speaker power-on delay bypassed or not, and which settings being used. Refer to Application Reference Guide, Page 1 Register 81.
