CHARACTERISTICS AND SPECIFICATIONS

•

Min / Max characteristics and specifications are guaranteed over the Specified Operating Conditions.

•

•

GND = 0 V. Single-ended voltages with respect to GND, differential voltages with respect to opposite half.

•

Device is connected as shown in Figure 9 on page 14 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. Channel-to-channel gain accuracy is directly proportional to the voltage reference absolute accuracy.

4. VREF inputs must satisfy: VA-

≤ VREF- < VREF+ ≤ VA+.

ABSOLUTE MAXIMUM RATINGS

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 ±100 mA will not cause SCR latch-up.

6. Includes continuous over-voltage conditions at the modulator analog input pins.
