NOTES
1Temperature ranges are as follows: B Version, –40°C to +105°C.
2Relative Accuracy is calculated using a reduced digital code range of 15 to 245.
3Gain Error is specified between Codes 15 and 245. The actual error at Code 15 is typically 3 LSB.
4Internal Voltage Reference Error = (Actual VREF – Ideal VREF/Ideal VREF) • 100. Ideal VREF = VDD/2, actual VREF = voltage on reference pin when internal reference
is selected.
Specifications subject to change without notice.
