Note 1:
All devices are 100% production tested at TA = +25°C. Specifications over temperature limits are guaranteed by Maxim Integrated’s bench or proprietary automated test equipment (ATE) characterization.
Note 2:
Specifications are guaranteed by Maxim Integrated’s bench characterization and by 100% production test using proprietary ATE setup and conditions.
Note 3:
For design guidance only. Not production tested.
Note 4:
These specifications are guaranteed by design, characterization, or I2C protocol.
