NOTES: (1) Junction temperature = ambient for 25

°C guaranteed specifications.

(2) Junction temperature = ambient at low temperature limit: junction temperature = ambient +20

°C at high temperature limit for over temperature guaranteed

specifications.

(3) Test Levels: (A) 100% tested at 25

°C. Over temperature limits by characterization and simulation. (B) Limits set by characterization and simulation.

(C) Typical value only for information.

(5) Tested < 3dB below minimum specified CMRR at

±CMIR limits.
