1. CHARACTERISTICS AND SPECIFICATIONS
• Min/Max characteristics and specifications are guaranteed over the Specified Operating Conditions.
• Typical performance characteristics and specifications are derived from measurements taken at nom-
inal supply voltages and TA = 25°C.
• GND = 0 V, all voltages with respect to 0 V.
• Device connected as shown in Figure 11 and Figure 12 unless otherwise noted.

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. Channel-to-channel gain accuracy is directly proportional to the voltage reference absolute accuracy.
4. VREF inputs must satisfy: VA- ≤ VREF- < VREF+ ≤ VA+.

WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
Notes: 5. Transient currents up to 100mA will not cause SCR latch-up.
6. Includes continuous over-voltage conditions on the analog input pins.
