Specifications subject to change without notice.
Temperature range as follows: J, K, L, GL versions, 0°C to +70°C; A, B, C, GC versions, –25°C to +85°C; S, T, U GU versions, –55°C to +125°C.
This includes the effect of 5 ppm max gain TC.
Guaranteed but not tested.
DB0–DB11 = 0 V to V
Feedthrough can be further reduced by connecting the metal lid on the ceramic package (Suffix D) to DGND.
Logic inputs are MOS gates. Typical input current (+25°C) is less than 1 nA.
Sample tested at +25°C to ensure compliance.
