1 Standard I2C mode operation guaranteed by design.
2 During power-up, the output is momentarily preset to midscale before restoring EEPROM content.
3 Delay time after power-on PRESET prior to writing new EEPROM data.
4 Endurance is qualified to 100,000 cycles per JEDEC Std. 22 method A117, and is measured at –40°C, +25°C, and +125°C; typical endurance at +25°C is 700,000 cycles.
5 Retention lifetime equivalent at junction temperature (TJ) = 55°C per JEDEC Std. 22, Method A117. Retention lifetime based on an activation energy of 0.6 eV derates
with junction temperature.
