Specifications subject to change without notice.
Temperature ranges are as follows: B Version, –40 C to +105 C.
Relative Accuracy is calculated using a reduced digital code range of 15 to 245.
Gain Error is specified between Codes 15 and 245. The actual error at Code 15 is typically 3 LSB.
Internal Voltage Reference Error = (Actual V
