Notes:
1. Tested in production
2. Based on characterization of 30 pieces over temperature on evaluation board or in socket
3. Based on design, through modeling and simulation across PVT
4. Typical. Randomly selected part measured at room temperature on evaluation board or in socket
5. Based on characterization of 5 pieces over temperature
6. Tested on 5 parts at room temperature
