2
Relative Accuracy is calculated using a reduced code range of 15 to 245.
3
Gain error is specified between Codes 15 and 245. The actual error at Code 15 is typically 3 LSB.
4
Guaranteed by characterization at product release, not production tested.
Specifications subject to change without notice.
