When operating on other supply voltages, see the Absolute Maximum Ratings section, Figure 11, and Table 5 for more information. 5 Internal resistors are trimmed to be ratio matched but have ±20% absolute accuracy. 6 See Figure 25 to Figure 28 in the Typical Performance Characteristics section for more information.
