1 Temperature ranges are as follows: A, B, C versions: 40°C to +85°C; J, L versions: 0°C to 70°C.
2 Reference input resistance is code-dependent, minimum at 0x8555.
3 Guaranteed by design, not subject to production test.
TIMING CHARACTERISTICS
VDD = 2.7 V to 5.5 V ±10%, VREF= 2.5 V, VINH = 3 V and 90% of VDD, VINL = 0 V and 10% of VDD, AGND = DGND = 0 V; 40°C < TA <
+85°C, unless otherwise noted.
