Hi Support Team,
I am assuming the DVDD current for ADAU1452 is to be maximum 40mA. Now when I need to calculate the power dissipation in the external pass transistor, I simply do (3.3 - 1.2) * 40mA. Now this comes to be around 84 mW. But if we see the recommended transistor as per datasheet, it is a high wattage transistor. Why is this? Is the current assumption wrong?
