Test Conditions/Comments
Drift after 1000 hours, ¾ scale output, TJ = 150°C
External RSET
Internal RSET
The dc-to-dc converter has been characterized
with a maximum load of 1 kΩ, chosen such that
compliance is not exceeded; see Figure 52 and
DC-DC MaxV bits in Table 25
For specified performance
TA = 25°C
At 10 kHz
Drift after 1000 hours, TJ = 150°C
See Figure 63
See Figure 64
