1 Typical represents average readings at 25°C, VDD = 5 V.
2 All dynamic characteristics use VDD = 5 V.
3 Guaranteed by design and not subject to production test.
4 Bandwidth, noise, and settling time are dependent on the terminal resistance value chosen. The lowest R value results in the fastest settling time and highest
bandwidth. The highest R value results in the minimum overall power consumption.
5 See Figure 2 for the location of measured values.
6 Endurance is qualified to 100,000 cycles as per JEDEC Std. 22 Method A117 and measured at 40°C, +25°C, and +85°C. Typical endurance at 25°C is 700,000 cycles.
7 Retention lifetime equivalent at junction temperature (TJ) = 55°C as per JEDEC Std. 22, Method A117. Retention lifetime based on an activation energy of 0.6 eV
derates with junction temperature.
