(1)

Junction temperature = ambient for +25

°C specifications.

(2)

Junction temperature = ambient at low temperature limits; junction temperature = ambient +28

°C at high temperature limit for over temperature 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.

(4)

Current is considered positive out of pin.

(5)

Tested < 3dB below minimum specified CMRR at
