Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Continuous operation above the specified maximum operating
junction temperature may impair device reliability.
Note 3: LTC2641-16/LTC2642-16 ±1LSB = ±0.0015% = ±15.3ppm of full
scale. LTC2641-14/LTC2642-14 ±1LSB = ±0.006% = ±61ppm of full scale.
LTC2641-12/LTC2642-12 ±1LSB = ±0.024% = ±244ppm of full scale.
