CHARACTERISTICS AND SPECIFICATIONS
•
Min / Max characteristics and specifications are guaranteed over the
Specified Operating Conditions
.
•
Typical performance characteristics and specifications are measured at nominal supply voltages and T
A
= 25
°C.
•
GND = 0 V. Single-ended voltages with respect to GND, differential voltages with respect to opposite half.
•
Device is connected as shown in
unless otherwise noted.
SPECIFIED OPERATING CONDITIONS
Notes: 1. VA- must always be the most-negative input voltage to avoid potential SCR latch-up conditions.
2. By design, a 2.500 V voltage reference input results in the best signal-to-noise performance.
3. Full-scale accuracy is directly proportional to the voltage reference absolute accuracy.
4. VREF inputs must satisfy: VA- < VREF- < VREF+ < VA+.
