1 See the Explanation of Test Levels section.

2 All ac specifications tested by driving ENCODE and ENCODE differentially. Reference Figure 18 for performance vs. encode power.

3 Digital output logic levels: DVCC = 3.3 V, CLOAD = 10 pF. Capacitive loads >10 pF degrade performance.

SWITCHING SPECIFICATIONS

AVCC = 5 V, DVCC = 3.3 V; ENCODE and ENCODE = maximum conversion rate MSPS; TMIN = –25°C, TMAX = +85°C, unless otherwise noted.
